Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489378, here are decompositions:

  • 11 + 489367 = 489378
  • 17 + 489361 = 489378
  • 41 + 489337 = 489378
  • 79 + 489299 = 489378
  • 137 + 489241 = 489378
  • 139 + 489239 = 489378
  • 181 + 489197 = 489378
  • 199 + 489179 = 489378

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 489,378 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 489378 first appears in π at position 908,110 of the decimal expansion (the 908,110ordinal-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.
