Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045020, here are decompositions:
- 7 + 1045013 = 1045020
- 17 + 1045003 = 1045020
- 23 + 1044997 = 1045020
- 79 + 1044941 = 1045020
- 89 + 1044931 = 1045020
- 127 + 1044893 = 1045020
- 131 + 1044889 = 1045020
- 173 + 1044847 = 1045020
Showing the first eight; more decompositions exist.
