Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720086, here are decompositions:

5 + 8720081 = 8720086
29 + 8720057 = 8720086
59 + 8720027 = 8720086
239 + 8719847 = 8720086
269 + 8719817 = 8720086
383 + 8719703 = 8720086
509 + 8719577 = 8720086
719 + 8719367 = 8720086

Showing the first eight; more decompositions exist.
