Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144930, here are decompositions:

13 + 144917 = 144930
31 + 144899 = 144930
41 + 144889 = 144930
43 + 144887 = 144930
47 + 144883 = 144930
83 + 144847 = 144930
101 + 144829 = 144930
113 + 144817 = 144930

Showing the first eight; more decompositions exist.
