Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532514, here are decompositions:
- 7 + 31532507 = 31532514
- 17 + 31532497 = 31532514
- 37 + 31532477 = 31532514
- 113 + 31532401 = 31532514
- 173 + 31532341 = 31532514
- 191 + 31532323 = 31532514
- 311 + 31532203 = 31532514
- 347 + 31532167 = 31532514
Showing the first eight; more decompositions exist.
