Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529844, here are decompositions:
- 61 + 31529783 = 31529844
- 127 + 31529717 = 31529844
- 163 + 31529681 = 31529844
- 167 + 31529677 = 31529844
- 173 + 31529671 = 31529844
- 193 + 31529651 = 31529844
- 251 + 31529593 = 31529844
- 277 + 31529567 = 31529844
Showing the first eight; more decompositions exist.
