Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542920, here are decompositions:
- 43 + 31542877 = 31542920
- 109 + 31542811 = 31542920
- 193 + 31542727 = 31542920
- 223 + 31542697 = 31542920
- 307 + 31542613 = 31542920
- 373 + 31542547 = 31542920
- 397 + 31542523 = 31542920
- 433 + 31542487 = 31542920
Showing the first eight; more decompositions exist.
