Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541454, here are decompositions:
- 5 + 31541449 = 31541454
- 17 + 31541437 = 31541454
- 37 + 31541417 = 31541454
- 53 + 31541401 = 31541454
- 107 + 31541347 = 31541454
- 157 + 31541297 = 31541454
- 173 + 31541281 = 31541454
- 211 + 31541243 = 31541454
Showing the first eight; more decompositions exist.
