Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476008, here are decompositions:

79 + 31475929 = 31476008
97 + 31475911 = 31476008
181 + 31475827 = 31476008
211 + 31475797 = 31476008
229 + 31475779 = 31476008
331 + 31475677 = 31476008
397 + 31475611 = 31476008
409 + 31475599 = 31476008

Showing the first eight; more decompositions exist.
