Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487558, here are decompositions:

89 + 487469 = 487558
101 + 487457 = 487558
131 + 487427 = 487558
167 + 487391 = 487558
251 + 487307 = 487558
311 + 487247 = 487558
347 + 487211 = 487558
479 + 487079 = 487558

Showing the first eight; more decompositions exist.
