Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522944, here are decompositions:
- 7 + 31522937 = 31522944
- 43 + 31522901 = 31522944
- 71 + 31522873 = 31522944
- 97 + 31522847 = 31522944
- 197 + 31522747 = 31522944
- 227 + 31522717 = 31522944
- 251 + 31522693 = 31522944
- 281 + 31522663 = 31522944
Showing the first eight; more decompositions exist.
