Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736786, here are decompositions:

5 + 8736781 = 8736786
59 + 8736727 = 8736786
67 + 8736719 = 8736786
83 + 8736703 = 8736786
103 + 8736683 = 8736786
127 + 8736659 = 8736786
139 + 8736647 = 8736786
193 + 8736593 = 8736786

Showing the first eight; more decompositions exist.
