Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617956, here are decompositions:
- 3 + 31617953 = 31617956
- 67 + 31617889 = 31617956
- 79 + 31617877 = 31617956
- 103 + 31617853 = 31617956
- 193 + 31617763 = 31617956
- 199 + 31617757 = 31617956
- 277 + 31617679 = 31617956
- 283 + 31617673 = 31617956
Showing the first eight; more decompositions exist.
