Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723626, here are decompositions:

17 + 8723609 = 8723626
167 + 8723459 = 8723626
227 + 8723399 = 8723626
239 + 8723387 = 8723626
383 + 8723243 = 8723626
503 + 8723123 = 8723626
563 + 8723063 = 8723626
677 + 8722949 = 8723626

Showing the first eight; more decompositions exist.
