Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61156, here are decompositions:
- 3 + 61153 = 61156
- 5 + 61151 = 61156
- 113 + 61043 = 61156
- 149 + 61007 = 61156
- 233 + 60923 = 61156
- 239 + 60917 = 61156
- 257 + 60899 = 61156
- 269 + 60887 = 61156
Showing the first eight; more decompositions exist.

The digit sequence 61156 first appears in π at position 127,893 of the decimal expansion (the 127,893ordinal-suffix:rd 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.
