Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498998, here are decompositions:

37 + 498961 = 498998
61 + 498937 = 498998
67 + 498931 = 498998
139 + 498859 = 498998
211 + 498787 = 498998
307 + 498691 = 498998
421 + 498577 = 498998
601 + 498397 = 498998

Showing the first eight; more decompositions exist.
