Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8692490, here are decompositions:

3 + 8692487 = 8692490
7 + 8692483 = 8692490
61 + 8692429 = 8692490
73 + 8692417 = 8692490
97 + 8692393 = 8692490
139 + 8692351 = 8692490
151 + 8692339 = 8692490
181 + 8692309 = 8692490

Showing the first eight; more decompositions exist.
