Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42490, here are decompositions:

3 + 42487 = 42490
17 + 42473 = 42490
23 + 42467 = 42490
29 + 42461 = 42490
47 + 42443 = 42490
53 + 42437 = 42490
83 + 42407 = 42490
131 + 42359 = 42490

Showing the first eight; more decompositions exist.
