Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487212, here are decompositions:

29 + 487183 = 487212
79 + 487133 = 487212
101 + 487111 = 487212
113 + 487099 = 487212
139 + 487073 = 487212
163 + 487049 = 487212
191 + 487021 = 487212
199 + 487013 = 487212

Showing the first eight; more decompositions exist.
