Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526644, here are decompositions:
- 11 + 31526633 = 31526644
- 41 + 31526603 = 31526644
- 167 + 31526477 = 31526644
- 257 + 31526387 = 31526644
- 293 + 31526351 = 31526644
- 431 + 31526213 = 31526644
- 503 + 31526141 = 31526644
- 557 + 31526087 = 31526644
Showing the first eight; more decompositions exist.
