Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672372, here are decompositions:

19 + 8672353 = 8672372
109 + 8672263 = 8672372
211 + 8672161 = 8672372
271 + 8672101 = 8672372
661 + 8671711 = 8672372
733 + 8671639 = 8672372
739 + 8671633 = 8672372
823 + 8671549 = 8672372

Showing the first eight; more decompositions exist.
