Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672780, here are decompositions:

7 + 8672773 = 8672780
13 + 8672767 = 8672780
73 + 8672707 = 8672780
139 + 8672641 = 8672780
229 + 8672551 = 8672780
241 + 8672539 = 8672780
271 + 8672509 = 8672780
373 + 8672407 = 8672780

Showing the first eight; more decompositions exist.
