Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487440, here are decompositions:

11 + 487429 = 487440
13 + 487427 = 487440
17 + 487423 = 487440
43 + 487397 = 487440
53 + 487387 = 487440
59 + 487381 = 487440
127 + 487313 = 487440
137 + 487303 = 487440

Showing the first eight; more decompositions exist.
