Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555998, here are decompositions:

31 + 555967 = 555998
67 + 555931 = 555998
127 + 555871 = 555998
307 + 555691 = 555998
337 + 555661 = 555998
409 + 555589 = 555998
577 + 555421 = 555998
607 + 555391 = 555998

Showing the first eight; more decompositions exist.
