Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532454, here are decompositions:
- 17 + 31532437 = 31532454
- 53 + 31532401 = 31532454
- 101 + 31532353 = 31532454
- 113 + 31532341 = 31532454
- 131 + 31532323 = 31532454
- 193 + 31532261 = 31532454
- 227 + 31532227 = 31532454
- 251 + 31532203 = 31532454
Showing the first eight; more decompositions exist.
