Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047986, here are decompositions:

7 + 1047979 = 1047986
103 + 1047883 = 1047986
127 + 1047859 = 1047986
223 + 1047763 = 1047986
283 + 1047703 = 1047986
337 + 1047649 = 1047986
397 + 1047589 = 1047986
487 + 1047499 = 1047986

Showing the first eight; more decompositions exist.
