Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449466, here are decompositions:

3 + 31449463 = 31449466
17 + 31449449 = 31449466
89 + 31449377 = 31449466
107 + 31449359 = 31449466
179 + 31449287 = 31449466
233 + 31449233 = 31449466
383 + 31449083 = 31449466
449 + 31449017 = 31449466

Showing the first eight; more decompositions exist.
