Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38490, here are decompositions:

29 + 38461 = 38490
31 + 38459 = 38490
37 + 38453 = 38490
41 + 38449 = 38490
43 + 38447 = 38490
59 + 38431 = 38490
97 + 38393 = 38490
113 + 38377 = 38490

Showing the first eight; more decompositions exist.
