Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047788, here are decompositions:

37 + 1047751 = 1047788
67 + 1047721 = 1047788
97 + 1047691 = 1047788
139 + 1047649 = 1047788
199 + 1047589 = 1047788
229 + 1047559 = 1047788
277 + 1047511 = 1047788
397 + 1047391 = 1047788

Showing the first eight; more decompositions exist.
