Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612646, here are decompositions:

5 + 8612641 = 8612646
13 + 8612633 = 8612646
17 + 8612629 = 8612646
19 + 8612627 = 8612646
149 + 8612497 = 8612646
167 + 8612479 = 8612646
173 + 8612473 = 8612646
223 + 8612423 = 8612646

Showing the first eight; more decompositions exist.
