Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449544, here are decompositions:

17 + 31449527 = 31449544
167 + 31449377 = 31449544
257 + 31449287 = 31449544
281 + 31449263 = 31449544
311 + 31449233 = 31449544
353 + 31449191 = 31449544
461 + 31449083 = 31449544
491 + 31449053 = 31449544

Showing the first eight; more decompositions exist.
