Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142762, here are decompositions:
- 3 + 142759 = 142762
- 5 + 142757 = 142762
- 29 + 142733 = 142762
- 89 + 142673 = 142762
- 173 + 142589 = 142762
- 233 + 142529 = 142762
- 293 + 142469 = 142762
- 359 + 142403 = 142762
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 142,762 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 142762 first appears in π at position 489,418 of the decimal expansion (the 489,418ordinal-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.
