Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162970, here are decompositions:

23 + 162947 = 162970
53 + 162917 = 162970
89 + 162881 = 162970
131 + 162839 = 162970
149 + 162821 = 162970
179 + 162791 = 162970
191 + 162779 = 162970
239 + 162731 = 162970

Showing the first eight; more decompositions exist.
