Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491482, here are decompositions:

53 + 491429 = 491482
59 + 491423 = 491482
149 + 491333 = 491482
263 + 491219 = 491482
269 + 491213 = 491482
281 + 491201 = 491482
311 + 491171 = 491482
353 + 491129 = 491482

Showing the first eight; more decompositions exist.
