Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047880, here are decompositions:
- 47 + 1047833 = 1047880
- 59 + 1047821 = 1047880
- 101 + 1047779 = 1047880
- 107 + 1047773 = 1047880
- 167 + 1047713 = 1047880
- 179 + 1047701 = 1047880
- 191 + 1047689 = 1047880
- 227 + 1047653 = 1047880
Showing the first eight; more decompositions exist.
