Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738490, here are decompositions:

17 + 8738473 = 8738490
41 + 8738449 = 8738490
43 + 8738447 = 8738490
53 + 8738437 = 8738490
83 + 8738407 = 8738490
107 + 8738383 = 8738490
113 + 8738377 = 8738490
127 + 8738363 = 8738490

Showing the first eight; more decompositions exist.
