Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142710, here are decompositions:

11 + 142699 = 142710
13 + 142697 = 142710
37 + 142673 = 142710
53 + 142657 = 142710
101 + 142609 = 142710
103 + 142607 = 142710
109 + 142601 = 142710
137 + 142573 = 142710

Showing the first eight; more decompositions exist.
