Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 961818, here are decompositions:
- 5 + 961813 = 961818
- 7 + 961811 = 961818
- 29 + 961789 = 961818
- 41 + 961777 = 961818
- 61 + 961757 = 961818
- 71 + 961747 = 961818
- 79 + 961739 = 961818
- 89 + 961729 = 961818
Showing the first eight; more decompositions exist.
