Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723132, here are decompositions:

43 + 8723089 = 8723132
79 + 8723053 = 8723132
139 + 8722993 = 8723132
151 + 8722981 = 8723132
163 + 8722969 = 8723132
241 + 8722891 = 8723132
421 + 8722711 = 8723132
661 + 8722471 = 8723132

Showing the first eight; more decompositions exist.
