Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149870, here are decompositions:

3 + 149867 = 149870
31 + 149839 = 149870
43 + 149827 = 149870
67 + 149803 = 149870
79 + 149791 = 149870
103 + 149767 = 149870
139 + 149731 = 149870
157 + 149713 = 149870

Showing the first eight; more decompositions exist.
