Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143562, here are decompositions:
- 11 + 143551 = 143562
- 43 + 143519 = 143562
- 53 + 143509 = 143562
- 59 + 143503 = 143562
- 61 + 143501 = 143562
- 73 + 143489 = 143562
- 79 + 143483 = 143562
- 101 + 143461 = 143562
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 143,562 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 143562 first appears in π at position 5,475 of the decimal expansion (the 5,475ordinal-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.
