Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472944, here are decompositions:
- 17 + 31472927 = 31472944
- 53 + 31472891 = 31472944
- 131 + 31472813 = 31472944
- 137 + 31472807 = 31472944
- 281 + 31472663 = 31472944
- 311 + 31472633 = 31472944
- 353 + 31472591 = 31472944
- 443 + 31472501 = 31472944
Showing the first eight; more decompositions exist.
