Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541796, here are decompositions:
- 59 + 31541737 = 31541796
- 89 + 31541707 = 31541796
- 103 + 31541693 = 31541796
- 137 + 31541659 = 31541796
- 163 + 31541633 = 31541796
- 199 + 31541597 = 31541796
- 227 + 31541569 = 31541796
- 233 + 31541563 = 31541796
Showing the first eight; more decompositions exist.
