Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029980, here are decompositions:
- 13 + 1029967 = 1029980
- 37 + 1029943 = 1029980
- 43 + 1029937 = 1029980
- 73 + 1029907 = 1029980
- 97 + 1029883 = 1029980
- 139 + 1029841 = 1029980
- 157 + 1029823 = 1029980
- 223 + 1029757 = 1029980
Showing the first eight; more decompositions exist.
