Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723562, here are decompositions:

11 + 8723551 = 8723562
31 + 8723531 = 8723562
41 + 8723521 = 8723562
79 + 8723483 = 8723562
83 + 8723479 = 8723562
103 + 8723459 = 8723562
139 + 8723423 = 8723562
163 + 8723399 = 8723562

Showing the first eight; more decompositions exist.
