Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152170, here are decompositions:

23 + 152147 = 152170
47 + 152123 = 152170
59 + 152111 = 152170
89 + 152081 = 152170
107 + 152063 = 152170
131 + 152039 = 152170
167 + 152003 = 152170
233 + 151937 = 152170

Showing the first eight; more decompositions exist.
