Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487888, here are decompositions:

59 + 487829 = 487888
131 + 487757 = 487888
179 + 487709 = 487888
197 + 487691 = 487888
239 + 487649 = 487888
251 + 487637 = 487888
281 + 487607 = 487888
419 + 487469 = 487888

Showing the first eight; more decompositions exist.
