Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623772, here are decompositions:

43 + 8623729 = 8623772
151 + 8623621 = 8623772
193 + 8623579 = 8623772
349 + 8623423 = 8623772
379 + 8623393 = 8623772
433 + 8623339 = 8623772
523 + 8623249 = 8623772
631 + 8623141 = 8623772

Showing the first eight; more decompositions exist.
