Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487450, here are decompositions:

3 + 487447 = 487450
23 + 487427 = 487450
53 + 487397 = 487450
59 + 487391 = 487450
101 + 487349 = 487450
137 + 487313 = 487450
167 + 487283 = 487450
239 + 487211 = 487450

Showing the first eight; more decompositions exist.
