Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491320, here are decompositions:

23 + 491297 = 491320
41 + 491279 = 491320
47 + 491273 = 491320
59 + 491261 = 491320
101 + 491219 = 491320
107 + 491213 = 491320
149 + 491171 = 491320
191 + 491129 = 491320

Showing the first eight; more decompositions exist.
