Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541544, here are decompositions:
- 17 + 31541527 = 31541544
- 37 + 31541507 = 31541544
- 61 + 31541483 = 31541544
- 107 + 31541437 = 31541544
- 127 + 31541417 = 31541544
- 197 + 31541347 = 31541544
- 263 + 31541281 = 31541544
- 277 + 31541267 = 31541544
Showing the first eight; more decompositions exist.
