Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162940, here are decompositions:

3 + 162937 = 162940
23 + 162917 = 162940
59 + 162881 = 162940
101 + 162839 = 162940
149 + 162791 = 162940
191 + 162749 = 162940
227 + 162713 = 162940
257 + 162683 = 162940

Showing the first eight; more decompositions exist.
