Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487752, here are decompositions:

11 + 487741 = 487752
19 + 487733 = 487752
43 + 487709 = 487752
61 + 487691 = 487752
71 + 487681 = 487752
101 + 487651 = 487752
103 + 487649 = 487752
149 + 487603 = 487752

Showing the first eight; more decompositions exist.
