Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144642, here are decompositions:

13 + 144629 = 144642
31 + 144611 = 144642
53 + 144589 = 144642
59 + 144583 = 144642
73 + 144569 = 144642
79 + 144563 = 144642
101 + 144541 = 144642
103 + 144539 = 144642

Showing the first eight; more decompositions exist.
