Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448008, here are decompositions:

41 + 31447967 = 31448008
47 + 31447961 = 31448008
107 + 31447901 = 31448008
197 + 31447811 = 31448008
239 + 31447769 = 31448008
257 + 31447751 = 31448008
401 + 31447607 = 31448008
479 + 31447529 = 31448008

Showing the first eight; more decompositions exist.
