Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142476, here are decompositions:
- 7 + 142469 = 142476
- 23 + 142453 = 142476
- 43 + 142433 = 142476
- 73 + 142403 = 142476
- 107 + 142369 = 142476
- 149 + 142327 = 142476
- 157 + 142319 = 142476
- 179 + 142297 = 142476
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 142,476 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 142476 first appears in π at position 761,068 of the decimal expansion (the 761,068ordinal-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.
