Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529948, here are decompositions:
- 67 + 31529881 = 31529948
- 199 + 31529749 = 31529948
- 271 + 31529677 = 31529948
- 277 + 31529671 = 31529948
- 397 + 31529551 = 31529948
- 409 + 31529539 = 31529948
- 601 + 31529347 = 31529948
- 691 + 31529257 = 31529948
Showing the first eight; more decompositions exist.
