Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145968, here are decompositions:

5 + 145963 = 145968
19 + 145949 = 145968
37 + 145931 = 145968
71 + 145897 = 145968
89 + 145879 = 145968
107 + 145861 = 145968
139 + 145829 = 145968
149 + 145819 = 145968

Showing the first eight; more decompositions exist.
