Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681490, here are decompositions:

7 + 8681483 = 8681490
17 + 8681473 = 8681490
23 + 8681467 = 8681490
43 + 8681447 = 8681490
61 + 8681429 = 8681490
89 + 8681401 = 8681490
113 + 8681377 = 8681490
127 + 8681363 = 8681490

Showing the first eight; more decompositions exist.
