Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709578, here are decompositions:

109 + 8709469 = 8709578
277 + 8709301 = 8709578
307 + 8709271 = 8709578
349 + 8709229 = 8709578
439 + 8709139 = 8709578
457 + 8709121 = 8709578
499 + 8709079 = 8709578
571 + 8709007 = 8709578

Showing the first eight; more decompositions exist.
