Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489400, here are decompositions:

  • 11 + 489389 = 489400
  • 71 + 489329 = 489400
  • 101 + 489299 = 489400
  • 137 + 489263 = 489400
  • 239 + 489161 = 489400
  • 347 + 489053 = 489400
  • 389 + 489011 = 489400
  • 419 + 488981 = 489400

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 489,400 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 489400 first appears in π at position 704,011 of the decimal expansion (the 704,011ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
