Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547976, here are decompositions:
- 17 + 31547959 = 31547976
- 23 + 31547953 = 31547976
- 43 + 31547933 = 31547976
- 59 + 31547917 = 31547976
- 127 + 31547849 = 31547976
- 137 + 31547839 = 31547976
- 139 + 31547837 = 31547976
- 193 + 31547783 = 31547976
Showing the first eight; more decompositions exist.
