Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448012, here are decompositions:

61 + 31447951 = 31448012
109 + 31447903 = 31448012
199 + 31447813 = 31448012
229 + 31447783 = 31448012
331 + 31447681 = 31448012
439 + 31447573 = 31448012
571 + 31447441 = 31448012
619 + 31447393 = 31448012

Showing the first eight; more decompositions exist.
