Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723782, here are decompositions:

173 + 8723609 = 8723782
251 + 8723531 = 8723782
359 + 8723423 = 8723782
383 + 8723399 = 8723782
461 + 8723321 = 8723782
479 + 8723303 = 8723782
569 + 8723213 = 8723782
659 + 8723123 = 8723782

Showing the first eight; more decompositions exist.
