Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545782, here are decompositions:
- 19 + 31545763 = 31545782
- 43 + 31545739 = 31545782
- 283 + 31545499 = 31545782
- 313 + 31545469 = 31545782
- 409 + 31545373 = 31545782
- 439 + 31545343 = 31545782
- 571 + 31545211 = 31545782
- 601 + 31545181 = 31545782
Showing the first eight; more decompositions exist.
