Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142626, here are decompositions:

7 + 142619 = 142626
17 + 142609 = 142626
19 + 142607 = 142626
37 + 142589 = 142626
53 + 142573 = 142626
59 + 142567 = 142626
67 + 142559 = 142626
73 + 142553 = 142626

Showing the first eight; more decompositions exist.
