Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542452, here are decompositions:
- 13 + 31542439 = 31542452
- 61 + 31542391 = 31542452
- 79 + 31542373 = 31542452
- 223 + 31542229 = 31542452
- 349 + 31542103 = 31542452
- 421 + 31542031 = 31542452
- 439 + 31542013 = 31542452
- 463 + 31541989 = 31542452
Showing the first eight; more decompositions exist.
