Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723042, here are decompositions:

43 + 8722999 = 8723042
61 + 8722981 = 8723042
73 + 8722969 = 8723042
151 + 8722891 = 8723042
331 + 8722711 = 8723042
421 + 8722621 = 8723042
439 + 8722603 = 8723042
571 + 8722471 = 8723042

Showing the first eight; more decompositions exist.
