Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487246, here are decompositions:

59 + 487187 = 487246
113 + 487133 = 487246
167 + 487079 = 487246
173 + 487073 = 487246
197 + 487049 = 487246
233 + 487013 = 487246
239 + 487007 = 487246
269 + 486977 = 487246

Showing the first eight; more decompositions exist.
