Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590008, here are decompositions:

31 + 31589977 = 31590008
139 + 31589869 = 31590008
181 + 31589827 = 31590008
271 + 31589737 = 31590008
277 + 31589731 = 31590008
349 + 31589659 = 31590008
397 + 31589611 = 31590008
547 + 31589461 = 31590008

Showing the first eight; more decompositions exist.
