Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723012, here are decompositions:

13 + 8722999 = 8723012
19 + 8722993 = 8723012
31 + 8722981 = 8723012
43 + 8722969 = 8723012
223 + 8722789 = 8723012
409 + 8722603 = 8723012
541 + 8722471 = 8723012
619 + 8722393 = 8723012

Showing the first eight; more decompositions exist.
