Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487422, here are decompositions:

31 + 487391 = 487422
41 + 487381 = 487422
59 + 487363 = 487422
73 + 487349 = 487422
109 + 487313 = 487422
139 + 487283 = 487422
211 + 487211 = 487422
239 + 487183 = 487422

Showing the first eight; more decompositions exist.
