Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525878, here are decompositions:
- 29 + 31525849 = 31525878
- 37 + 31525841 = 31525878
- 61 + 31525817 = 31525878
- 67 + 31525811 = 31525878
- 79 + 31525799 = 31525878
- 101 + 31525777 = 31525878
- 107 + 31525771 = 31525878
- 179 + 31525699 = 31525878
Showing the first eight; more decompositions exist.
