Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723036, here are decompositions:

19 + 8723017 = 8723036
37 + 8722999 = 8723036
43 + 8722993 = 8723036
67 + 8722969 = 8723036
433 + 8722603 = 8723036
577 + 8722459 = 8723036
607 + 8722429 = 8723036
613 + 8722423 = 8723036

Showing the first eight; more decompositions exist.
