Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449496, here are decompositions:

3 + 31449493 = 31449496
17 + 31449479 = 31449496
47 + 31449449 = 31449496
137 + 31449359 = 31449496
173 + 31449323 = 31449496
233 + 31449263 = 31449496
263 + 31449233 = 31449496
317 + 31449179 = 31449496

Showing the first eight; more decompositions exist.
