Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507738, here are decompositions:

19 + 507719 = 507738
41 + 507697 = 507738
47 + 507691 = 507738
71 + 507667 = 507738
97 + 507641 = 507738
107 + 507631 = 507738
131 + 507607 = 507738
139 + 507599 = 507738

Showing the first eight; more decompositions exist.
