Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630786, here are decompositions:

7 + 8630779 = 8630786
37 + 8630749 = 8630786
103 + 8630683 = 8630786
139 + 8630647 = 8630786
193 + 8630593 = 8630786
337 + 8630449 = 8630786
547 + 8630239 = 8630786
607 + 8630179 = 8630786

Showing the first eight; more decompositions exist.
