Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597776, here are decompositions:
- 13 + 31597763 = 31597776
- 37 + 31597739 = 31597776
- 47 + 31597729 = 31597776
- 59 + 31597717 = 31597776
- 79 + 31597697 = 31597776
- 83 + 31597693 = 31597776
- 103 + 31597673 = 31597776
- 137 + 31597639 = 31597776
Showing the first eight; more decompositions exist.
