Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653780, here are decompositions:

11 + 8653769 = 8653780
17 + 8653763 = 8653780
71 + 8653709 = 8653780
89 + 8653691 = 8653780
101 + 8653679 = 8653780
167 + 8653613 = 8653780
227 + 8653553 = 8653780
251 + 8653529 = 8653780

Showing the first eight; more decompositions exist.
