Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559206, here are decompositions:
- 17 + 31559189 = 31559206
- 113 + 31559093 = 31559206
- 137 + 31559069 = 31559206
- 179 + 31559027 = 31559206
- 233 + 31558973 = 31559206
- 347 + 31558859 = 31559206
- 359 + 31558847 = 31559206
- 383 + 31558823 = 31559206
Showing the first eight; more decompositions exist.
