Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612490, here are decompositions:

11 + 8612479 = 8612490
17 + 8612473 = 8612490
53 + 8612437 = 8612490
67 + 8612423 = 8612490
79 + 8612411 = 8612490
179 + 8612311 = 8612490
191 + 8612299 = 8612490
197 + 8612293 = 8612490

Showing the first eight; more decompositions exist.
