Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487564, here are decompositions:

3 + 487561 = 487564
83 + 487481 = 487564
101 + 487463 = 487564
107 + 487457 = 487564
137 + 487427 = 487564
167 + 487397 = 487564
173 + 487391 = 487564
251 + 487313 = 487564

Showing the first eight; more decompositions exist.
