Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544406, here are decompositions:
- 13 + 31544393 = 31544406
- 43 + 31544363 = 31544406
- 59 + 31544347 = 31544406
- 83 + 31544323 = 31544406
- 109 + 31544297 = 31544406
- 193 + 31544213 = 31544406
- 199 + 31544207 = 31544406
- 227 + 31544179 = 31544406
Showing the first eight; more decompositions exist.
