Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732786, here are decompositions:

37 + 8732749 = 8732786
43 + 8732743 = 8732786
67 + 8732719 = 8732786
109 + 8732677 = 8732786
193 + 8732593 = 8732786
313 + 8732473 = 8732786
487 + 8732299 = 8732786
547 + 8732239 = 8732786

Showing the first eight; more decompositions exist.
