Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741490, here are decompositions:

11 + 8741479 = 8741490
19 + 8741471 = 8741490
31 + 8741459 = 8741490
53 + 8741437 = 8741490
59 + 8741431 = 8741490
89 + 8741401 = 8741490
97 + 8741393 = 8741490
127 + 8741363 = 8741490

Showing the first eight; more decompositions exist.
