Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497152, here are decompositions:
- 13 + 31497139 = 31497152
- 19 + 31497133 = 31497152
- 151 + 31497001 = 31497152
- 163 + 31496989 = 31497152
- 373 + 31496779 = 31497152
- 433 + 31496719 = 31497152
- 541 + 31496611 = 31497152
- 601 + 31496551 = 31497152
Showing the first eight; more decompositions exist.
