Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507538, here are decompositions:

41 + 507497 = 507538
47 + 507491 = 507538
107 + 507431 = 507538
137 + 507401 = 507538
167 + 507371 = 507538
179 + 507359 = 507538
191 + 507347 = 507538
389 + 507149 = 507538

Showing the first eight; more decompositions exist.
