Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532724, here are decompositions:
- 31 + 31532693 = 31532724
- 37 + 31532687 = 31532724
- 71 + 31532653 = 31532724
- 127 + 31532597 = 31532724
- 131 + 31532593 = 31532724
- 137 + 31532587 = 31532724
- 151 + 31532573 = 31532724
- 173 + 31532551 = 31532724
Showing the first eight; more decompositions exist.
