Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487492, here are decompositions:

3 + 487489 = 487492
11 + 487481 = 487492
23 + 487469 = 487492
29 + 487463 = 487492
101 + 487391 = 487492
179 + 487313 = 487492
281 + 487211 = 487492
359 + 487133 = 487492

Showing the first eight; more decompositions exist.
