Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626852, here are decompositions:
- 11 + 31626841 = 31626852
- 13 + 31626839 = 31626852
- 163 + 31626689 = 31626852
- 233 + 31626619 = 31626852
- 263 + 31626589 = 31626852
- 281 + 31626571 = 31626852
- 353 + 31626499 = 31626852
- 359 + 31626493 = 31626852
Showing the first eight; more decompositions exist.
