Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671232, here are decompositions:

13 + 8671219 = 8671232
181 + 8671051 = 8671232
223 + 8671009 = 8671232
313 + 8670919 = 8671232
421 + 8670811 = 8671232
523 + 8670709 = 8671232
613 + 8670619 = 8671232
643 + 8670589 = 8671232

Showing the first eight; more decompositions exist.
