Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 588, here are decompositions:

11 + 577 = 588
17 + 571 = 588
19 + 569 = 588
31 + 557 = 588
41 + 547 = 588
47 + 541 = 588
67 + 521 = 588
79 + 509 = 588

Showing the first eight; more decompositions exist.
