Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162390, here are decompositions:

31 + 162359 = 162390
47 + 162343 = 162390
97 + 162293 = 162390
101 + 162289 = 162390
103 + 162287 = 162390
113 + 162277 = 162390
127 + 162263 = 162390
139 + 162251 = 162390

Showing the first eight; more decompositions exist.
