Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545732, here are decompositions:
- 19 + 31545713 = 31545732
- 103 + 31545629 = 31545732
- 109 + 31545623 = 31545732
- 233 + 31545499 = 31545732
- 263 + 31545469 = 31545732
- 293 + 31545439 = 31545732
- 331 + 31545401 = 31545732
- 353 + 31545379 = 31545732
Showing the first eight; more decompositions exist.
