Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448006, here are decompositions:

19 + 31447987 = 31448006
43 + 31447963 = 31448006
103 + 31447903 = 31448006
193 + 31447813 = 31448006
223 + 31447783 = 31448006
349 + 31447657 = 31448006
379 + 31447627 = 31448006
433 + 31447573 = 31448006

Showing the first eight; more decompositions exist.
