Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498818, here are decompositions:

31 + 498787 = 498818
37 + 498781 = 498818
79 + 498739 = 498818
127 + 498691 = 498818
139 + 498679 = 498818
241 + 498577 = 498818
349 + 498469 = 498818
379 + 498439 = 498818

Showing the first eight; more decompositions exist.
