Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15704, here are decompositions:

37 + 15667 = 15704
43 + 15661 = 15704
61 + 15643 = 15704
97 + 15607 = 15704
103 + 15601 = 15704
163 + 15541 = 15704
193 + 15511 = 15704
211 + 15493 = 15704

Showing the first eight; more decompositions exist.
