Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529376, here are decompositions:
- 17 + 31529359 = 31529376
- 23 + 31529353 = 31529376
- 29 + 31529347 = 31529376
- 97 + 31529279 = 31529376
- 103 + 31529273 = 31529376
- 107 + 31529269 = 31529376
- 127 + 31529249 = 31529376
- 157 + 31529219 = 31529376
Showing the first eight; more decompositions exist.
