Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507998, here are decompositions:

19 + 507979 = 507998
37 + 507961 = 507998
61 + 507937 = 507998
79 + 507919 = 507998
97 + 507901 = 507998
241 + 507757 = 507998
307 + 507691 = 507998
331 + 507667 = 507998

Showing the first eight; more decompositions exist.
