Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507440, here are decompositions:

19 + 507421 = 507440
79 + 507361 = 507440
127 + 507313 = 507440
139 + 507301 = 507440
151 + 507289 = 507440
223 + 507217 = 507440
277 + 507163 = 507440
331 + 507109 = 507440

Showing the first eight; more decompositions exist.
