Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617962, here are decompositions:
- 3 + 31617959 = 31617962
- 73 + 31617889 = 31617962
- 109 + 31617853 = 31617962
- 151 + 31617811 = 31617962
- 199 + 31617763 = 31617962
- 283 + 31617679 = 31617962
- 331 + 31617631 = 31617962
- 379 + 31617583 = 31617962
Showing the first eight; more decompositions exist.
