Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657770, here are decompositions:

3 + 8657767 = 8657770
47 + 8657723 = 8657770
71 + 8657699 = 8657770
83 + 8657687 = 8657770
89 + 8657681 = 8657770
131 + 8657639 = 8657770
137 + 8657633 = 8657770
257 + 8657513 = 8657770

Showing the first eight; more decompositions exist.
