Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529532, here are decompositions:
- 11 + 31529521 = 31529532
- 53 + 31529479 = 31529532
- 61 + 31529471 = 31529532
- 101 + 31529431 = 31529532
- 173 + 31529359 = 31529532
- 179 + 31529353 = 31529532
- 211 + 31529321 = 31529532
- 263 + 31529269 = 31529532
Showing the first eight; more decompositions exist.
