Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019018, here are decompositions:
- 19 + 1018999 = 1019018
- 31 + 1018987 = 1019018
- 37 + 1018981 = 1019018
- 61 + 1018957 = 1019018
- 139 + 1018879 = 1019018
- 211 + 1018807 = 1019018
- 229 + 1018789 = 1019018
- 241 + 1018777 = 1019018
Showing the first eight; more decompositions exist.
