Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761646, here are decompositions:

7 + 8761639 = 8761646
13 + 8761633 = 8761646
109 + 8761537 = 8761646
139 + 8761507 = 8761646
193 + 8761453 = 8761646
307 + 8761339 = 8761646
349 + 8761297 = 8761646
367 + 8761279 = 8761646

Showing the first eight; more decompositions exist.
