Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723458, here are decompositions:

17 + 8723441 = 8723458
59 + 8723399 = 8723458
71 + 8723387 = 8723458
137 + 8723321 = 8723458
467 + 8722991 = 8723458
509 + 8722949 = 8723458
599 + 8722859 = 8723458
617 + 8722841 = 8723458

Showing the first eight; more decompositions exist.
