Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142782, here are decompositions:

11 + 142771 = 142782
23 + 142759 = 142782
71 + 142711 = 142782
83 + 142699 = 142782
109 + 142673 = 142782
163 + 142619 = 142782
173 + 142609 = 142782
181 + 142601 = 142782

Showing the first eight; more decompositions exist.
