Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623780, here are decompositions:

17 + 8623763 = 8623780
23 + 8623757 = 8623780
29 + 8623751 = 8623780
59 + 8623721 = 8623780
101 + 8623679 = 8623780
197 + 8623583 = 8623780
233 + 8623547 = 8623780
251 + 8623529 = 8623780

Showing the first eight; more decompositions exist.
