Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529526, here are decompositions:
- 5 + 31529521 = 31529526
- 19 + 31529507 = 31529526
- 47 + 31529479 = 31529526
- 79 + 31529447 = 31529526
- 113 + 31529413 = 31529526
- 167 + 31529359 = 31529526
- 173 + 31529353 = 31529526
- 179 + 31529347 = 31529526
Showing the first eight; more decompositions exist.
