Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142672, here are decompositions:
- 53 + 142619 = 142672
- 71 + 142601 = 142672
- 83 + 142589 = 142672
- 113 + 142559 = 142672
- 239 + 142433 = 142672
- 251 + 142421 = 142672
- 269 + 142403 = 142672
- 281 + 142391 = 142672
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 142,672 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 142672 first appears in π at position 707,261 of the decimal expansion (the 707,261ordinal-suffix:st 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.
