Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 662, here are decompositions:

3 + 659 = 662
19 + 643 = 662
31 + 631 = 662
43 + 619 = 662
61 + 601 = 662
139 + 523 = 662
163 + 499 = 662
199 + 463 = 662

Showing the first eight; more decompositions exist.
