Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 608, here are decompositions:

7 + 601 = 608
31 + 577 = 608
37 + 571 = 608
61 + 547 = 608
67 + 541 = 608
109 + 499 = 608
151 + 457 = 608
199 + 409 = 608

Showing the first eight; more decompositions exist.
