Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532394, here are decompositions:
- 41 + 31532353 = 31532394
- 53 + 31532341 = 31532394
- 71 + 31532323 = 31532394
- 167 + 31532227 = 31532394
- 191 + 31532203 = 31532394
- 227 + 31532167 = 31532394
- 277 + 31532117 = 31532394
- 281 + 31532113 = 31532394
Showing the first eight; more decompositions exist.
