Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142810, here are decompositions:

11 + 142799 = 142810
23 + 142787 = 142810
53 + 142757 = 142810
113 + 142697 = 142810
137 + 142673 = 142810
191 + 142619 = 142810
251 + 142559 = 142810
257 + 142553 = 142810

Showing the first eight; more decompositions exist.
