Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7988, here are decompositions:

37 + 7951 = 7988
61 + 7927 = 7988
109 + 7879 = 7988
199 + 7789 = 7988
229 + 7759 = 7988
271 + 7717 = 7988
307 + 7681 = 7988
349 + 7639 = 7988

Showing the first eight; more decompositions exist.
