Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142498, here are decompositions:
- 29 + 142469 = 142498
- 71 + 142427 = 142498
- 107 + 142391 = 142498
- 179 + 142319 = 142498
- 227 + 142271 = 142498
- 281 + 142217 = 142498
- 347 + 142151 = 142498
- 401 + 142097 = 142498
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 142,498 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 142498 first appears in π at position 54,425 of the decimal expansion (the 54,425ordinal-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.
