Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528452, here are decompositions:
- 5 + 31528447 = 31528452
- 19 + 31528433 = 31528452
- 79 + 31528373 = 31528452
- 89 + 31528363 = 31528452
- 103 + 31528349 = 31528452
- 139 + 31528313 = 31528452
- 173 + 31528279 = 31528452
- 211 + 31528241 = 31528452
Showing the first eight; more decompositions exist.
