Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673780, here are decompositions:

19 + 8673761 = 8673780
53 + 8673727 = 8673780
97 + 8673683 = 8673780
103 + 8673677 = 8673780
179 + 8673601 = 8673780
211 + 8673569 = 8673780
233 + 8673547 = 8673780
263 + 8673517 = 8673780

Showing the first eight; more decompositions exist.
