Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529964, here are decompositions:
- 31 + 31529933 = 31529964
- 41 + 31529923 = 31529964
- 73 + 31529891 = 31529964
- 83 + 31529881 = 31529964
- 181 + 31529783 = 31529964
- 283 + 31529681 = 31529964
- 293 + 31529671 = 31529964
- 313 + 31529651 = 31529964
Showing the first eight; more decompositions exist.
