Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681746, here are decompositions:

53 + 8681693 = 8681746
83 + 8681663 = 8681746
107 + 8681639 = 8681746
167 + 8681579 = 8681746
179 + 8681567 = 8681746
197 + 8681549 = 8681746
233 + 8681513 = 8681746
239 + 8681507 = 8681746

Showing the first eight; more decompositions exist.
