Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541324, here are decompositions:
- 43 + 31541281 = 31541324
- 151 + 31541173 = 31541324
- 163 + 31541161 = 31541324
- 211 + 31541113 = 31541324
- 223 + 31541101 = 31541324
- 277 + 31541047 = 31541324
- 307 + 31541017 = 31541324
- 457 + 31540867 = 31541324
Showing the first eight; more decompositions exist.
