Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493618, here are decompositions:

11 + 493607 = 493618
137 + 493481 = 493618
317 + 493301 = 493618
401 + 493217 = 493618
449 + 493169 = 493618
479 + 493139 = 493618
491 + 493127 = 493618
509 + 493109 = 493618

Showing the first eight; more decompositions exist.
