Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657764, here are decompositions:

41 + 8657723 = 8657764
83 + 8657681 = 8657764
113 + 8657651 = 8657764
131 + 8657633 = 8657764
197 + 8657567 = 8657764
251 + 8657513 = 8657764
383 + 8657381 = 8657764
431 + 8657333 = 8657764

Showing the first eight; more decompositions exist.
