Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7888, here are decompositions:

5 + 7883 = 7888
11 + 7877 = 7888
47 + 7841 = 7888
59 + 7829 = 7888
71 + 7817 = 7888
131 + 7757 = 7888
197 + 7691 = 7888
239 + 7649 = 7888

Showing the first eight; more decompositions exist.
