Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541464, here are decompositions:
- 47 + 31541417 = 31541464
- 167 + 31541297 = 31541464
- 197 + 31541267 = 31541464
- 347 + 31541117 = 31541464
- 443 + 31541021 = 31541464
- 503 + 31540961 = 31541464
- 593 + 31540871 = 31541464
- 641 + 31540823 = 31541464
Showing the first eight; more decompositions exist.
