Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008980, here are decompositions:
- 43 + 1008937 = 1008980
- 67 + 1008913 = 1008980
- 79 + 1008901 = 1008980
- 109 + 1008871 = 1008980
- 127 + 1008853 = 1008980
- 151 + 1008829 = 1008980
- 163 + 1008817 = 1008980
- 199 + 1008781 = 1008980
Showing the first eight; more decompositions exist.
