Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529744, here are decompositions:
- 67 + 31529677 = 31529744
- 73 + 31529671 = 31529744
- 151 + 31529593 = 31529744
- 193 + 31529551 = 31529744
- 223 + 31529521 = 31529744
- 313 + 31529431 = 31529744
- 331 + 31529413 = 31529744
- 397 + 31529347 = 31529744
Showing the first eight; more decompositions exist.
