Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477008, here are decompositions:

61 + 31476947 = 31477008
127 + 31476881 = 31477008
137 + 31476871 = 31477008
179 + 31476829 = 31477008
281 + 31476727 = 31477008
317 + 31476691 = 31477008
397 + 31476611 = 31477008
401 + 31476607 = 31477008

Showing the first eight; more decompositions exist.
