Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144906, here are decompositions:

7 + 144899 = 144906
17 + 144889 = 144906
19 + 144887 = 144906
23 + 144883 = 144906
59 + 144847 = 144906
67 + 144839 = 144906
89 + 144817 = 144906
127 + 144779 = 144906

Showing the first eight; more decompositions exist.
