Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162266, here are decompositions:

3 + 162263 = 162266
37 + 162229 = 162266
157 + 162109 = 162266
283 + 161983 = 162266
397 + 161869 = 162266
487 + 161779 = 162266
523 + 161743 = 162266
607 + 161659 = 162266

Showing the first eight; more decompositions exist.
