Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1010, here are decompositions:
- 13 + 997 = 1010
- 19 + 991 = 1010
- 43 + 967 = 1010
- 73 + 937 = 1010
- 103 + 907 = 1010
- 127 + 883 = 1010
- 151 + 859 = 1010
- 157 + 853 = 1010
Showing the first eight; more decompositions exist.

The digit sequence 1010 first appears in π at position 852 of the decimal expansion (the 852ordinal-suffix:nd 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.
