Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491202, here are decompositions:

31 + 491171 = 491202
43 + 491159 = 491202
53 + 491149 = 491202
73 + 491129 = 491202
163 + 491039 = 491202
199 + 491003 = 491202
211 + 490991 = 491202
233 + 490969 = 491202

Showing the first eight; more decompositions exist.
