Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723814, here are decompositions:

7 + 8723807 = 8723814
83 + 8723731 = 8723814
107 + 8723707 = 8723814
137 + 8723677 = 8723814
263 + 8723551 = 8723814
283 + 8723531 = 8723814
293 + 8723521 = 8723814
317 + 8723497 = 8723814

Showing the first eight; more decompositions exist.
