Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7718, here are decompositions:

19 + 7699 = 7718
31 + 7687 = 7718
37 + 7681 = 7718
79 + 7639 = 7718
97 + 7621 = 7718
127 + 7591 = 7718
157 + 7561 = 7718
181 + 7537 = 7718

Showing the first eight; more decompositions exist.
