Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529540, here are decompositions:
- 19 + 31529521 = 31529540
- 61 + 31529479 = 31529540
- 109 + 31529431 = 31529540
- 127 + 31529413 = 31529540
- 181 + 31529359 = 31529540
- 193 + 31529347 = 31529540
- 271 + 31529269 = 31529540
- 283 + 31529257 = 31529540
Showing the first eight; more decompositions exist.
