Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144972, here are decompositions:

5 + 144967 = 144972
11 + 144961 = 144972
31 + 144941 = 144972
41 + 144931 = 144972
73 + 144899 = 144972
83 + 144889 = 144972
89 + 144883 = 144972
181 + 144791 = 144972

Showing the first eight; more decompositions exist.
