Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525866, here are decompositions:
- 17 + 31525849 = 31525866
- 67 + 31525799 = 31525866
- 79 + 31525787 = 31525866
- 83 + 31525783 = 31525866
- 89 + 31525777 = 31525866
- 103 + 31525763 = 31525866
- 149 + 31525717 = 31525866
- 167 + 31525699 = 31525866
Showing the first eight; more decompositions exist.
