Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545488, here are decompositions:
- 19 + 31545469 = 31545488
- 97 + 31545391 = 31545488
- 109 + 31545379 = 31545488
- 157 + 31545331 = 31545488
- 277 + 31545211 = 31545488
- 307 + 31545181 = 31545488
- 397 + 31545091 = 31545488
- 421 + 31545067 = 31545488
Showing the first eight; more decompositions exist.
