Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487738, here are decompositions:

5 + 487733 = 487738
11 + 487727 = 487738
29 + 487709 = 487738
47 + 487691 = 487738
89 + 487649 = 487738
101 + 487637 = 487738
131 + 487607 = 487738
137 + 487601 = 487738

Showing the first eight; more decompositions exist.
