Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162380, here are decompositions:

37 + 162343 = 162380
103 + 162277 = 162380
151 + 162229 = 162380
271 + 162109 = 162380
373 + 162007 = 162380
397 + 161983 = 162380
409 + 161971 = 162380
433 + 161947 = 162380

Showing the first eight; more decompositions exist.
