Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487164, here are decompositions:

31 + 487133 = 487164
53 + 487111 = 487164
71 + 487093 = 487164
107 + 487057 = 487164
113 + 487051 = 487164
151 + 487013 = 487164
157 + 487007 = 487164
173 + 486991 = 487164

Showing the first eight; more decompositions exist.
