Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700490, here are decompositions:

17 + 8700473 = 8700490
23 + 8700467 = 8700490
41 + 8700449 = 8700490
59 + 8700431 = 8700490
83 + 8700407 = 8700490
89 + 8700401 = 8700490
107 + 8700383 = 8700490
137 + 8700353 = 8700490

Showing the first eight; more decompositions exist.
