Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506818, here are decompositions:

89 + 506729 = 506818
131 + 506687 = 506818
227 + 506591 = 506818
281 + 506537 = 506818
311 + 506507 = 506818
317 + 506501 = 506818
359 + 506459 = 506818
401 + 506417 = 506818

Showing the first eight; more decompositions exist.
