Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489530, here are decompositions:

  • 37 + 489493 = 489530
  • 43 + 489487 = 489530
  • 73 + 489457 = 489530
  • 103 + 489427 = 489530
  • 163 + 489367 = 489530
  • 193 + 489337 = 489530
  • 313 + 489217 = 489530
  • 373 + 489157 = 489530

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 489,530 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 489530 first appears in π at position 155,399 of the decimal expansion (the 155,399ordinal-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.
