Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487442, here are decompositions:

13 + 487429 = 487442
19 + 487423 = 487442
61 + 487381 = 487442
79 + 487363 = 487442
139 + 487303 = 487442
181 + 487261 = 487442
223 + 487219 = 487442
229 + 487213 = 487442

Showing the first eight; more decompositions exist.
