Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538008, here are decompositions:

11 + 31537997 = 31538008
137 + 31537871 = 31538008
149 + 31537859 = 31538008
317 + 31537691 = 31538008
449 + 31537559 = 31538008
461 + 31537547 = 31538008
599 + 31537409 = 31538008
617 + 31537391 = 31538008

Showing the first eight; more decompositions exist.
