Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697782, here are decompositions:

3 + 8697779 = 8697782
13 + 8697769 = 8697782
271 + 8697511 = 8697782
283 + 8697499 = 8697782
349 + 8697433 = 8697782
439 + 8697343 = 8697782
619 + 8697163 = 8697782
733 + 8697049 = 8697782

Showing the first eight; more decompositions exist.
