Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491236, here are decompositions:

17 + 491219 = 491236
23 + 491213 = 491236
107 + 491129 = 491236
197 + 491039 = 491236
233 + 491003 = 491236
269 + 490967 = 491236
359 + 490877 = 491236
467 + 490769 = 491236

Showing the first eight; more decompositions exist.
