Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449634, here are decompositions:

5 + 31449629 = 31449634
23 + 31449611 = 31449634
53 + 31449581 = 31449634
107 + 31449527 = 31449634
233 + 31449401 = 31449634
257 + 31449377 = 31449634
311 + 31449323 = 31449634
347 + 31449287 = 31449634

Showing the first eight; more decompositions exist.
