Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527752, here are decompositions:
- 43 + 31527709 = 31527752
- 211 + 31527541 = 31527752
- 229 + 31527523 = 31527752
- 271 + 31527481 = 31527752
- 409 + 31527343 = 31527752
- 499 + 31527253 = 31527752
- 541 + 31527211 = 31527752
- 601 + 31527151 = 31527752
Showing the first eight; more decompositions exist.
