Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525784, here are decompositions:
- 7 + 31525777 = 31525784
- 13 + 31525771 = 31525784
- 61 + 31525723 = 31525784
- 67 + 31525717 = 31525784
- 97 + 31525687 = 31525784
- 127 + 31525657 = 31525784
- 181 + 31525603 = 31525784
- 307 + 31525477 = 31525784
Showing the first eight; more decompositions exist.
