Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487582, here are decompositions:

101 + 487481 = 487582
113 + 487469 = 487582
191 + 487391 = 487582
233 + 487349 = 487582
269 + 487313 = 487582
449 + 487133 = 487582
503 + 487079 = 487582
509 + 487073 = 487582

Showing the first eight; more decompositions exist.
