Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577264, here are decompositions:
- 3 + 31577261 = 31577264
- 31 + 31577233 = 31577264
- 67 + 31577197 = 31577264
- 151 + 31577113 = 31577264
- 181 + 31577083 = 31577264
- 193 + 31577071 = 31577264
- 211 + 31577053 = 31577264
- 307 + 31576957 = 31577264
Showing the first eight; more decompositions exist.
