Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61000, here are decompositions:
- 47 + 60953 = 61000
- 83 + 60917 = 61000
- 101 + 60899 = 61000
- 113 + 60887 = 61000
- 131 + 60869 = 61000
- 179 + 60821 = 61000
- 227 + 60773 = 61000
- 239 + 60761 = 61000
Showing the first eight; more decompositions exist.

The digit sequence 61000 first appears in π at position 48,939 of the decimal expansion (the 48,939ordinal-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.
