Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487170, here are decompositions:

37 + 487133 = 487170
59 + 487111 = 487170
71 + 487099 = 487170
97 + 487073 = 487170
113 + 487057 = 487170
149 + 487021 = 487170
157 + 487013 = 487170
163 + 487007 = 487170

Showing the first eight; more decompositions exist.
