Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627008, here are decompositions:
- 29 + 31626979 = 31627008
- 31 + 31626977 = 31627008
- 41 + 31626967 = 31627008
- 109 + 31626899 = 31627008
- 139 + 31626869 = 31627008
- 151 + 31626857 = 31627008
- 167 + 31626841 = 31627008
- 181 + 31626827 = 31627008
Showing the first eight; more decompositions exist.
