Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56642, here are decompositions:

13 + 56629 = 56642
31 + 56611 = 56642
43 + 56599 = 56642
73 + 56569 = 56642
109 + 56533 = 56642
139 + 56503 = 56642
163 + 56479 = 56642
199 + 56443 = 56642

Showing the first eight; more decompositions exist.
