Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87776, here are decompositions:

37 + 87739 = 87776
79 + 87697 = 87776
97 + 87679 = 87776
127 + 87649 = 87776
163 + 87613 = 87776
193 + 87583 = 87776
223 + 87553 = 87776
229 + 87547 = 87776

Showing the first eight; more decompositions exist.
