Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160388, here are decompositions:

31 + 160357 = 160388
79 + 160309 = 160388
157 + 160231 = 160388
181 + 160207 = 160388
229 + 160159 = 160388
271 + 160117 = 160388
307 + 160081 = 160388
379 + 160009 = 160388

Showing the first eight; more decompositions exist.
