Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535944, here are decompositions:
- 3 + 31535941 = 31535944
- 5 + 31535939 = 31535944
- 113 + 31535831 = 31535944
- 191 + 31535753 = 31535944
- 197 + 31535747 = 31535944
- 227 + 31535717 = 31535944
- 263 + 31535681 = 31535944
- 311 + 31535633 = 31535944
Showing the first eight; more decompositions exist.
