Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723718, here are decompositions:

11 + 8723707 = 8723718
41 + 8723677 = 8723718
79 + 8723639 = 8723718
109 + 8723609 = 8723718
149 + 8723569 = 8723718
167 + 8723551 = 8723718
197 + 8723521 = 8723718
239 + 8723479 = 8723718

Showing the first eight; more decompositions exist.
