Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498418, here are decompositions:

17 + 498401 = 498418
191 + 498227 = 498418
251 + 498167 = 498418
317 + 498101 = 498418
419 + 497999 = 498418
449 + 497969 = 498418
461 + 497957 = 498418
587 + 497831 = 498418

Showing the first eight; more decompositions exist.
