Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144966, here are decompositions:

5 + 144961 = 144966
67 + 144899 = 144966
79 + 144887 = 144966
83 + 144883 = 144966
127 + 144839 = 144966
137 + 144829 = 144966
149 + 144817 = 144966
193 + 144773 = 144966

Showing the first eight; more decompositions exist.
