Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600780, here are decompositions:

3 + 8600777 = 8600780
37 + 8600743 = 8600780
61 + 8600719 = 8600780
79 + 8600701 = 8600780
103 + 8600677 = 8600780
151 + 8600629 = 8600780
193 + 8600587 = 8600780
271 + 8600509 = 8600780

Showing the first eight; more decompositions exist.
