Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612658, here are decompositions:

17 + 8612641 = 8612658
29 + 8612629 = 8612658
31 + 8612627 = 8612658
127 + 8612531 = 8612658
179 + 8612479 = 8612658
311 + 8612347 = 8612658
347 + 8612311 = 8612658
359 + 8612299 = 8612658

Showing the first eight; more decompositions exist.
