Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143008, here are decompositions:

29 + 142979 = 143008
59 + 142949 = 143008
101 + 142907 = 143008
137 + 142871 = 143008
167 + 142841 = 143008
197 + 142811 = 143008
251 + 142757 = 143008
311 + 142697 = 143008

Showing the first eight; more decompositions exist.
