Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144636, here are decompositions:

7 + 144629 = 144636
43 + 144593 = 144636
47 + 144589 = 144636
53 + 144583 = 144636
59 + 144577 = 144636
67 + 144569 = 144636
73 + 144563 = 144636
97 + 144539 = 144636

Showing the first eight; more decompositions exist.
