Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142952, here are decompositions:
- 3 + 142949 = 142952
- 13 + 142939 = 142952
- 79 + 142873 = 142952
- 163 + 142789 = 142952
- 181 + 142771 = 142952
- 193 + 142759 = 142952
- 241 + 142711 = 142952
- 379 + 142573 = 142952
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 142,952 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 142952 first appears in π at position 74,600 of the decimal expansion (the 74,600ordinal-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.
