Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723650, here are decompositions:

11 + 8723639 = 8723650
41 + 8723609 = 8723650
167 + 8723483 = 8723650
191 + 8723459 = 8723650
227 + 8723423 = 8723650
251 + 8723399 = 8723650
263 + 8723387 = 8723650
347 + 8723303 = 8723650

Showing the first eight; more decompositions exist.
