Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742856, here are decompositions:

167 + 8742689 = 8742856
179 + 8742677 = 8742856
233 + 8742623 = 8742856
359 + 8742497 = 8742856
503 + 8742353 = 8742856
509 + 8742347 = 8742856
593 + 8742263 = 8742856
659 + 8742197 = 8742856

Showing the first eight; more decompositions exist.
