Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541456, here are decompositions:
- 7 + 31541449 = 31541456
- 19 + 31541437 = 31541456
- 97 + 31541359 = 31541456
- 109 + 31541347 = 31541456
- 223 + 31541233 = 31541456
- 277 + 31541179 = 31541456
- 283 + 31541173 = 31541456
- 409 + 31541047 = 31541456
Showing the first eight; more decompositions exist.
