Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615700, here are decompositions:

7 + 8615693 = 8615700
43 + 8615657 = 8615700
47 + 8615653 = 8615700
109 + 8615591 = 8615700
113 + 8615587 = 8615700
157 + 8615543 = 8615700
173 + 8615527 = 8615700
193 + 8615507 = 8615700

Showing the first eight; more decompositions exist.
