Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162320, here are decompositions:

31 + 162289 = 162320
43 + 162277 = 162320
211 + 162109 = 162320
229 + 162091 = 162320
241 + 162079 = 162320
313 + 162007 = 162320
337 + 161983 = 162320
349 + 161971 = 162320

Showing the first eight; more decompositions exist.
