Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529952, here are decompositions:
- 19 + 31529933 = 31529952
- 29 + 31529923 = 31529952
- 53 + 31529899 = 31529952
- 61 + 31529891 = 31529952
- 71 + 31529881 = 31529952
- 109 + 31529843 = 31529952
- 271 + 31529681 = 31529952
- 281 + 31529671 = 31529952
Showing the first eight; more decompositions exist.
