Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487430, here are decompositions:

3 + 487427 = 487430
7 + 487423 = 487430
43 + 487387 = 487430
67 + 487363 = 487430
127 + 487303 = 487430
211 + 487219 = 487430
331 + 487099 = 487430
337 + 487093 = 487430

Showing the first eight; more decompositions exist.
