Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487158, here are decompositions:

47 + 487111 = 487158
59 + 487099 = 487158
79 + 487079 = 487158
101 + 487057 = 487158
107 + 487051 = 487158
109 + 487049 = 487158
137 + 487021 = 487158
151 + 487007 = 487158

Showing the first eight; more decompositions exist.
