Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526228, here are decompositions:
- 7 + 31526221 = 31526228
- 31 + 31526197 = 31526228
- 37 + 31526191 = 31526228
- 271 + 31525957 = 31526228
- 277 + 31525951 = 31526228
- 337 + 31525891 = 31526228
- 379 + 31525849 = 31526228
- 457 + 31525771 = 31526228
Showing the first eight; more decompositions exist.
