Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712922, here are decompositions:

3 + 8712919 = 8712922
59 + 8712863 = 8712922
173 + 8712749 = 8712922
293 + 8712629 = 8712922
311 + 8712611 = 8712922
389 + 8712533 = 8712922
431 + 8712491 = 8712922
599 + 8712323 = 8712922

Showing the first eight; more decompositions exist.
