Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487122, here are decompositions:

11 + 487111 = 487122
23 + 487099 = 487122
29 + 487093 = 487122
43 + 487079 = 487122
71 + 487051 = 487122
73 + 487049 = 487122
101 + 487021 = 487122
109 + 487013 = 487122

Showing the first eight; more decompositions exist.
