Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723632, here are decompositions:

23 + 8723609 = 8723632
101 + 8723531 = 8723632
149 + 8723483 = 8723632
173 + 8723459 = 8723632
191 + 8723441 = 8723632
233 + 8723399 = 8723632
311 + 8723321 = 8723632
389 + 8723243 = 8723632

Showing the first eight; more decompositions exist.
