Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542632, here are decompositions:
- 19 + 31542613 = 31542632
- 73 + 31542559 = 31542632
- 109 + 31542523 = 31542632
- 193 + 31542439 = 31542632
- 241 + 31542391 = 31542632
- 601 + 31542031 = 31542632
- 619 + 31542013 = 31542632
- 631 + 31542001 = 31542632
Showing the first eight; more decompositions exist.
