Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047998, here are decompositions:

19 + 1047979 = 1047998
37 + 1047961 = 1047998
139 + 1047859 = 1047998
157 + 1047841 = 1047998
277 + 1047721 = 1047998
307 + 1047691 = 1047998
331 + 1047667 = 1047998
349 + 1047649 = 1047998

Showing the first eight; more decompositions exist.
