Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144996, here are decompositions:

13 + 144983 = 144996
23 + 144973 = 144996
29 + 144967 = 144996
79 + 144917 = 144996
97 + 144899 = 144996
107 + 144889 = 144996
109 + 144887 = 144996
113 + 144883 = 144996

Showing the first eight; more decompositions exist.
