Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507990, here are decompositions:

11 + 507979 = 507990
19 + 507971 = 507990
29 + 507961 = 507990
37 + 507953 = 507990
53 + 507937 = 507990
71 + 507919 = 507990
73 + 507917 = 507990
83 + 507907 = 507990

Showing the first eight; more decompositions exist.
