Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529862, here are decompositions:
- 19 + 31529843 = 31529862
- 43 + 31529819 = 31529862
- 79 + 31529783 = 31529862
- 113 + 31529749 = 31529862
- 181 + 31529681 = 31529862
- 191 + 31529671 = 31529862
- 193 + 31529669 = 31529862
- 211 + 31529651 = 31529862
Showing the first eight; more decompositions exist.
