Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720056, here are decompositions:

29 + 8720027 = 8720056
113 + 8719943 = 8720056
239 + 8719817 = 8720056
353 + 8719703 = 8720056
479 + 8719577 = 8720056
677 + 8719379 = 8720056
857 + 8719199 = 8720056
929 + 8719127 = 8720056

Showing the first eight; more decompositions exist.
