Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723756, here are decompositions:

79 + 8723677 = 8723756
103 + 8723653 = 8723756
163 + 8723593 = 8723756
277 + 8723479 = 8723756
337 + 8723419 = 8723756
397 + 8723359 = 8723756
409 + 8723347 = 8723756
439 + 8723317 = 8723756

Showing the first eight; more decompositions exist.
