Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615776, here are decompositions:

5 + 8615771 = 8615776
53 + 8615723 = 8615776
83 + 8615693 = 8615776
233 + 8615543 = 8615776
263 + 8615513 = 8615776
269 + 8615507 = 8615776
353 + 8615423 = 8615776
443 + 8615333 = 8615776

Showing the first eight; more decompositions exist.
