Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723446, here are decompositions:

5 + 8723441 = 8723446
23 + 8723423 = 8723446
47 + 8723399 = 8723446
59 + 8723387 = 8723446
233 + 8723213 = 8723446
383 + 8723063 = 8723446
569 + 8722877 = 8723446
587 + 8722859 = 8723446

Showing the first eight; more decompositions exist.
