Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632490, here are decompositions:

3 + 8632487 = 8632490
37 + 8632453 = 8632490
67 + 8632423 = 8632490
79 + 8632411 = 8632490
103 + 8632387 = 8632490
109 + 8632381 = 8632490
127 + 8632363 = 8632490
157 + 8632333 = 8632490

Showing the first eight; more decompositions exist.
