Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142650, here are decompositions:

31 + 142619 = 142650
41 + 142609 = 142650
43 + 142607 = 142650
59 + 142591 = 142650
61 + 142589 = 142650
83 + 142567 = 142650
97 + 142553 = 142650
103 + 142547 = 142650

Showing the first eight; more decompositions exist.
