Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480088, here are decompositions:
- 67 + 31480021 = 31480088
- 127 + 31479961 = 31480088
- 139 + 31479949 = 31480088
- 271 + 31479817 = 31480088
- 331 + 31479757 = 31480088
- 349 + 31479739 = 31480088
- 439 + 31479649 = 31480088
- 499 + 31479589 = 31480088
Showing the first eight; more decompositions exist.
