Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723636, here are decompositions:

43 + 8723593 = 8723636
67 + 8723569 = 8723636
139 + 8723497 = 8723636
157 + 8723479 = 8723636
199 + 8723437 = 8723636
277 + 8723359 = 8723636
283 + 8723353 = 8723636
433 + 8723203 = 8723636

Showing the first eight; more decompositions exist.
