Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507388, here are decompositions:

5 + 507383 = 507388
17 + 507371 = 507388
29 + 507359 = 507388
41 + 507347 = 507388
59 + 507329 = 507388
71 + 507317 = 507388
191 + 507197 = 507388
239 + 507149 = 507388

Showing the first eight; more decompositions exist.
