Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507128, here are decompositions:

19 + 507109 = 507128
79 + 507049 = 507128
199 + 506929 = 507128
229 + 506899 = 507128
241 + 506887 = 507128
331 + 506797 = 507128
337 + 506791 = 507128
397 + 506731 = 507128

Showing the first eight; more decompositions exist.
