Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636786, here are decompositions:

7 + 8636779 = 8636786
73 + 8636713 = 8636786
97 + 8636689 = 8636786
139 + 8636647 = 8636786
199 + 8636587 = 8636786
313 + 8636473 = 8636786
337 + 8636449 = 8636786
397 + 8636389 = 8636786

Showing the first eight; more decompositions exist.
