Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498730, here are decompositions:

41 + 498689 = 498730
83 + 498647 = 498730
131 + 498599 = 498730
173 + 498557 = 498730
179 + 498551 = 498730
233 + 498497 = 498730
263 + 498467 = 498730
269 + 498461 = 498730

Showing the first eight; more decompositions exist.
