Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449212, here are decompositions:

313 + 31448899 = 31449212
349 + 31448863 = 31449212
373 + 31448839 = 31449212
409 + 31448803 = 31449212
499 + 31448713 = 31449212
631 + 31448581 = 31449212
661 + 31448551 = 31449212
733 + 31448479 = 31449212

Showing the first eight; more decompositions exist.
