Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12662, here are decompositions:

3 + 12659 = 12662
43 + 12619 = 12662
61 + 12601 = 12662
73 + 12589 = 12662
79 + 12583 = 12662
109 + 12553 = 12662
151 + 12511 = 12662
211 + 12451 = 12662

Showing the first eight; more decompositions exist.
