Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529872, here are decompositions:
- 29 + 31529843 = 31529872
- 53 + 31529819 = 31529872
- 89 + 31529783 = 31529872
- 191 + 31529681 = 31529872
- 401 + 31529471 = 31529872
- 593 + 31529279 = 31529872
- 599 + 31529273 = 31529872
- 653 + 31529219 = 31529872
Showing the first eight; more decompositions exist.
