Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738566, here are decompositions:

59 + 8738507 = 8738566
167 + 8738399 = 8738566
227 + 8738339 = 8738566
233 + 8738333 = 8738566
293 + 8738273 = 8738566
443 + 8738123 = 8738566
479 + 8738087 = 8738566
587 + 8737979 = 8738566

Showing the first eight; more decompositions exist.
