Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672156, here are decompositions:

109 + 8672047 = 8672156
487 + 8671669 = 8672156
523 + 8671633 = 8672156
607 + 8671549 = 8672156
709 + 8671447 = 8672156
907 + 8671249 = 8672156
937 + 8671219 = 8672156
1009 + 8671147 = 8672156

Showing the first eight; more decompositions exist.
