Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143946, here are decompositions:

37 + 143909 = 143946
67 + 143879 = 143946
73 + 143873 = 143946
113 + 143833 = 143946
139 + 143807 = 143946
149 + 143797 = 143946
167 + 143779 = 143946
227 + 143719 = 143946

Showing the first eight; more decompositions exist.
