Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535358, here are decompositions:

17 + 31535341 = 31535358
31 + 31535327 = 31535358
37 + 31535321 = 31535358
47 + 31535311 = 31535358
131 + 31535227 = 31535358
139 + 31535219 = 31535358
227 + 31535131 = 31535358
251 + 31535107 = 31535358

Showing the first eight; more decompositions exist.
