Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449604, here are decompositions:

23 + 31449581 = 31449604
47 + 31449557 = 31449604
227 + 31449377 = 31449604
281 + 31449323 = 31449604
317 + 31449287 = 31449604
521 + 31449083 = 31449604
587 + 31449017 = 31449604
617 + 31448987 = 31449604

Showing the first eight; more decompositions exist.
