Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38690, here are decompositions:

13 + 38677 = 38690
19 + 38671 = 38690
37 + 38653 = 38690
61 + 38629 = 38690
79 + 38611 = 38690
97 + 38593 = 38690
229 + 38461 = 38690
241 + 38449 = 38690

Showing the first eight; more decompositions exist.
