Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510998, here are decompositions:

67 + 510931 = 510998
79 + 510919 = 510998
109 + 510889 = 510998
151 + 510847 = 510998
181 + 510817 = 510998
307 + 510691 = 510998
379 + 510619 = 510998
409 + 510589 = 510998

Showing the first eight; more decompositions exist.
