Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162904, here are decompositions:

3 + 162901 = 162904
23 + 162881 = 162904
83 + 162821 = 162904
113 + 162791 = 162904
173 + 162731 = 162904
191 + 162713 = 162904
227 + 162677 = 162904
233 + 162671 = 162904

Showing the first eight; more decompositions exist.
