Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525852, here are decompositions:
- 3 + 31525849 = 31525852
- 11 + 31525841 = 31525852
- 41 + 31525811 = 31525852
- 53 + 31525799 = 31525852
- 89 + 31525763 = 31525852
- 251 + 31525601 = 31525852
- 263 + 31525589 = 31525852
- 353 + 31525499 = 31525852
Showing the first eight; more decompositions exist.
