Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657736, here are decompositions:

5 + 8657731 = 8657736
13 + 8657723 = 8657736
37 + 8657699 = 8657736
97 + 8657639 = 8657736
103 + 8657633 = 8657736
107 + 8657629 = 8657736
167 + 8657569 = 8657736
173 + 8657563 = 8657736

Showing the first eight; more decompositions exist.
