Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162778, here are decompositions:

29 + 162749 = 162778
47 + 162731 = 162778
101 + 162677 = 162778
107 + 162671 = 162778
137 + 162641 = 162778
149 + 162629 = 162778
167 + 162611 = 162778
251 + 162527 = 162778

Showing the first eight; more decompositions exist.
