Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498986, here are decompositions:

13 + 498973 = 498986
79 + 498907 = 498986
127 + 498859 = 498986
199 + 498787 = 498986
307 + 498679 = 498986
373 + 498613 = 498986
409 + 498577 = 498986
463 + 498523 = 498986

Showing the first eight; more decompositions exist.
