Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047816, here are decompositions:
- 37 + 1047779 = 1047816
- 43 + 1047773 = 1047816
- 53 + 1047763 = 1047816
- 79 + 1047737 = 1047816
- 103 + 1047713 = 1047816
- 113 + 1047703 = 1047816
- 127 + 1047689 = 1047816
- 149 + 1047667 = 1047816
Showing the first eight; more decompositions exist.
