Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87784, here are decompositions:

17 + 87767 = 87784
41 + 87743 = 87784
83 + 87701 = 87784
101 + 87683 = 87784
113 + 87671 = 87784
197 + 87587 = 87784
227 + 87557 = 87784
293 + 87491 = 87784

Showing the first eight; more decompositions exist.
