Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87554, here are decompositions:
- 7 + 87547 = 87554
- 13 + 87541 = 87554
- 31 + 87523 = 87554
- 37 + 87517 = 87554
- 43 + 87511 = 87554
- 73 + 87481 = 87554
- 127 + 87427 = 87554
- 151 + 87403 = 87554
Showing the first eight; more decompositions exist.

The digit sequence 87554 first appears in π at position 912 of the decimal expansion (the 912ordinal-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.
