Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449262, here are decompositions:

3 + 31449259 = 31449262
29 + 31449233 = 31449262
71 + 31449191 = 31449262
83 + 31449179 = 31449262
179 + 31449083 = 31449262
191 + 31449071 = 31449262
233 + 31449029 = 31449262
353 + 31448909 = 31449262

Showing the first eight; more decompositions exist.
