Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42662, here are decompositions:

13 + 42649 = 42662
19 + 42643 = 42662
73 + 42589 = 42662
163 + 42499 = 42662
199 + 42463 = 42662
211 + 42451 = 42662
229 + 42433 = 42662
271 + 42391 = 42662

Showing the first eight; more decompositions exist.
