Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487744, here are decompositions:

3 + 487741 = 487744
11 + 487733 = 487744
17 + 487727 = 487744
41 + 487703 = 487744
53 + 487691 = 487744
107 + 487637 = 487744
137 + 487607 = 487744
263 + 487481 = 487744

Showing the first eight; more decompositions exist.
