Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499430, here are decompositions:

7 + 499423 = 499430
67 + 499363 = 499430
103 + 499327 = 499430
109 + 499321 = 499430
163 + 499267 = 499430
241 + 499189 = 499430
271 + 499159 = 499430
313 + 499117 = 499430

Showing the first eight; more decompositions exist.
