Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627168, here are decompositions:

17 + 31627151 = 31627168
47 + 31627121 = 31627168
191 + 31626977 = 31627168
269 + 31626899 = 31627168
311 + 31626857 = 31627168
401 + 31626767 = 31627168
479 + 31626689 = 31627168
761 + 31626407 = 31627168

Showing the first eight; more decompositions exist.
