Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535908, here are decompositions:

29 + 31535879 = 31535908
167 + 31535741 = 31535908
191 + 31535717 = 31535908
227 + 31535681 = 31535908
251 + 31535657 = 31535908
269 + 31535639 = 31535908
317 + 31535591 = 31535908
359 + 31535549 = 31535908

Showing the first eight; more decompositions exist.
