Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498618, here are decompositions:

5 + 498613 = 498618
7 + 498611 = 498618
19 + 498599 = 498618
41 + 498577 = 498618
61 + 498557 = 498618
67 + 498551 = 498618
97 + 498521 = 498618
149 + 498469 = 498618

Showing the first eight; more decompositions exist.
