Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142826, here are decompositions:

37 + 142789 = 142826
67 + 142759 = 142826
127 + 142699 = 142826
283 + 142543 = 142826
373 + 142453 = 142826
457 + 142369 = 142826
499 + 142327 = 142826
643 + 142183 = 142826

Showing the first eight; more decompositions exist.
