Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612648, here are decompositions:

7 + 8612641 = 8612648
19 + 8612629 = 8612648
67 + 8612581 = 8612648
151 + 8612497 = 8612648
211 + 8612437 = 8612648
337 + 8612311 = 8612648
349 + 8612299 = 8612648
439 + 8612209 = 8612648

Showing the first eight; more decompositions exist.
