Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162284, here are decompositions:

7 + 162277 = 162284
193 + 162091 = 162284
277 + 162007 = 162284
307 + 161977 = 162284
313 + 161971 = 162284
337 + 161947 = 162284
373 + 161911 = 162284
523 + 161761 = 162284

Showing the first eight; more decompositions exist.
