Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142662, here are decompositions:

5 + 142657 = 142662
43 + 142619 = 142662
53 + 142609 = 142662
61 + 142601 = 142662
71 + 142591 = 142662
73 + 142589 = 142662
89 + 142573 = 142662
103 + 142559 = 142662

Showing the first eight; more decompositions exist.
