Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623784, here are decompositions:

67 + 8623717 = 8623784
97 + 8623687 = 8623784
163 + 8623621 = 8623784
181 + 8623603 = 8623784
523 + 8623261 = 8623784
571 + 8623213 = 8623784
643 + 8623141 = 8623784
661 + 8623123 = 8623784

Showing the first eight; more decompositions exist.
