Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 846, here are decompositions:
- 7 + 839 = 846
- 17 + 829 = 846
- 19 + 827 = 846
- 23 + 823 = 846
- 37 + 809 = 846
- 59 + 787 = 846
- 73 + 773 = 846
- 89 + 757 = 846
Showing the first eight; more decompositions exist.
