Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615782, here are decompositions:

11 + 8615771 = 8615782
59 + 8615723 = 8615782
89 + 8615693 = 8615782
191 + 8615591 = 8615782
239 + 8615543 = 8615782
269 + 8615513 = 8615782
311 + 8615471 = 8615782
359 + 8615423 = 8615782

Showing the first eight; more decompositions exist.
