Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522860, here are decompositions:
- 13 + 31522847 = 31522860
- 37 + 31522823 = 31522860
- 113 + 31522747 = 31522860
- 167 + 31522693 = 31522860
- 191 + 31522669 = 31522860
- 197 + 31522663 = 31522860
- 227 + 31522633 = 31522860
- 263 + 31522597 = 31522860
Showing the first eight; more decompositions exist.
