Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026740, here are decompositions:
- 7 + 1026733 = 1026740
- 31 + 1026709 = 1026740
- 61 + 1026679 = 1026740
- 67 + 1026673 = 1026740
- 73 + 1026667 = 1026740
- 79 + 1026661 = 1026740
- 157 + 1026583 = 1026740
- 163 + 1026577 = 1026740
Showing the first eight; more decompositions exist.
