Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143100, here are decompositions:
- 7 + 143093 = 143100
- 37 + 143063 = 143100
- 47 + 143053 = 143100
- 107 + 142993 = 143100
- 127 + 142973 = 143100
- 131 + 142969 = 143100
- 137 + 142963 = 143100
- 151 + 142949 = 143100
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 143,100 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 143100 first appears in π at position 926,139 of the decimal expansion (the 926,139ordinal-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.
