Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143902, here are decompositions:
- 23 + 143879 = 143902
- 29 + 143873 = 143902
- 71 + 143831 = 143902
- 89 + 143813 = 143902
- 173 + 143729 = 143902
- 191 + 143711 = 143902
- 233 + 143669 = 143902
- 251 + 143651 = 143902
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 143,902 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 143902 first appears in π at position 481,832 of the decimal expansion (the 481,832ordinal-suffix:nd 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.
