Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502008, here are decompositions:

29 + 31501979 = 31502008
71 + 31501937 = 31502008
101 + 31501907 = 31502008
227 + 31501781 = 31502008
257 + 31501751 = 31502008
281 + 31501727 = 31502008
347 + 31501661 = 31502008
389 + 31501619 = 31502008

Showing the first eight; more decompositions exist.
