Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628038, here are decompositions:
- 17 + 31628021 = 31628038
- 59 + 31627979 = 31628038
- 89 + 31627949 = 31628038
- 107 + 31627931 = 31628038
- 149 + 31627889 = 31628038
- 227 + 31627811 = 31628038
- 311 + 31627727 = 31628038
- 317 + 31627721 = 31628038
Showing the first eight; more decompositions exist.
