Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723776, here are decompositions:

137 + 8723639 = 8723776
167 + 8723609 = 8723776
293 + 8723483 = 8723776
317 + 8723459 = 8723776
353 + 8723423 = 8723776
389 + 8723387 = 8723776
563 + 8723213 = 8723776
653 + 8723123 = 8723776

Showing the first eight; more decompositions exist.
