Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529410, here are decompositions:
- 89 + 31529321 = 31529410
- 131 + 31529279 = 31529410
- 137 + 31529273 = 31529410
- 167 + 31529243 = 31529410
- 191 + 31529219 = 31529410
- 197 + 31529213 = 31529410
- 443 + 31528967 = 31529410
- 557 + 31528853 = 31529410
Showing the first eight; more decompositions exist.
