Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688786, here are decompositions:

47 + 8688739 = 8688786
79 + 8688707 = 8688786
83 + 8688703 = 8688786
89 + 8688697 = 8688786
157 + 8688629 = 8688786
173 + 8688613 = 8688786
179 + 8688607 = 8688786
193 + 8688593 = 8688786

Showing the first eight; more decompositions exist.
