Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498642, here are decompositions:

29 + 498613 = 498642
31 + 498611 = 498642
43 + 498599 = 498642
59 + 498583 = 498642
149 + 498493 = 498642
173 + 498469 = 498642
181 + 498461 = 498642
233 + 498409 = 498642

Showing the first eight; more decompositions exist.
