Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742766, here are decompositions:

89 + 8742677 = 8742766
113 + 8742653 = 8742766
269 + 8742497 = 8742766
317 + 8742449 = 8742766
419 + 8742347 = 8742766
449 + 8742317 = 8742766
503 + 8742263 = 8742766
569 + 8742197 = 8742766

Showing the first eight; more decompositions exist.
