Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529850, here are decompositions:
- 7 + 31529843 = 31529850
- 31 + 31529819 = 31529850
- 67 + 31529783 = 31529850
- 101 + 31529749 = 31529850
- 173 + 31529677 = 31529850
- 179 + 31529671 = 31529850
- 181 + 31529669 = 31529850
- 199 + 31529651 = 31529850
Showing the first eight; more decompositions exist.
