Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487546, here are decompositions:

83 + 487463 = 487546
89 + 487457 = 487546
149 + 487397 = 487546
197 + 487349 = 487546
233 + 487313 = 487546
239 + 487307 = 487546
263 + 487283 = 487546
359 + 487187 = 487546

Showing the first eight; more decompositions exist.
