Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 692, here are decompositions:

19 + 673 = 692
31 + 661 = 692
61 + 631 = 692
73 + 619 = 692
79 + 613 = 692
151 + 541 = 692
193 + 499 = 692
229 + 463 = 692

Showing the first eight; more decompositions exist.
