Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629780, here are decompositions:

17 + 8629763 = 8629780
41 + 8629739 = 8629780
101 + 8629679 = 8629780
167 + 8629613 = 8629780
197 + 8629583 = 8629780
347 + 8629433 = 8629780
431 + 8629349 = 8629780
587 + 8629193 = 8629780

Showing the first eight; more decompositions exist.
