Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495230, here are decompositions:

19 + 495211 = 495230
31 + 495199 = 495230
79 + 495151 = 495230
97 + 495133 = 495230
163 + 495067 = 495230
193 + 495037 = 495230
271 + 494959 = 495230
313 + 494917 = 495230

Showing the first eight; more decompositions exist.
