Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588006, here are decompositions:

3 + 31588003 = 31588006
83 + 31587923 = 31588006
113 + 31587893 = 31588006
227 + 31587779 = 31588006
239 + 31587767 = 31588006
257 + 31587749 = 31588006
269 + 31587737 = 31588006
347 + 31587659 = 31588006

Showing the first eight; more decompositions exist.
