Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639506, here are decompositions:

47 + 8639459 = 8639506
53 + 8639453 = 8639506
233 + 8639273 = 8639506
257 + 8639249 = 8639506
353 + 8639153 = 8639506
383 + 8639123 = 8639506
443 + 8639063 = 8639506
479 + 8639027 = 8639506

Showing the first eight; more decompositions exist.
