Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507728, here are decompositions:

31 + 507697 = 507728
37 + 507691 = 507728
61 + 507667 = 507728
97 + 507631 = 507728
139 + 507589 = 507728
157 + 507571 = 507728
229 + 507499 = 507728
307 + 507421 = 507728

Showing the first eight; more decompositions exist.
