Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449844, here are decompositions:

53 + 31449791 = 31449844
197 + 31449647 = 31449844
233 + 31449611 = 31449844
263 + 31449581 = 31449844
317 + 31449527 = 31449844
443 + 31449401 = 31449844
467 + 31449377 = 31449844
521 + 31449323 = 31449844

Showing the first eight; more decompositions exist.
