Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87774, here are decompositions:

7 + 87767 = 87774
23 + 87751 = 87774
31 + 87743 = 87774
53 + 87721 = 87774
73 + 87701 = 87774
83 + 87691 = 87774
103 + 87671 = 87774
131 + 87643 = 87774

Showing the first eight; more decompositions exist.
