Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487392, here are decompositions:

5 + 487387 = 487392
11 + 487381 = 487392
29 + 487363 = 487392
43 + 487349 = 487392
79 + 487313 = 487392
89 + 487303 = 487392
109 + 487283 = 487392
131 + 487261 = 487392

Showing the first eight; more decompositions exist.
