Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750086, here are decompositions:

17 + 8750069 = 8750086
47 + 8750039 = 8750086
53 + 8750033 = 8750086
239 + 8749847 = 8750086
269 + 8749817 = 8750086
353 + 8749733 = 8750086
479 + 8749607 = 8750086
617 + 8749469 = 8750086

Showing the first eight; more decompositions exist.
