Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547608, here are decompositions:

17 + 31547591 = 31547608
89 + 31547519 = 31547608
101 + 31547507 = 31547608
137 + 31547471 = 31547608
149 + 31547459 = 31547608
167 + 31547441 = 31547608
251 + 31547357 = 31547608
269 + 31547339 = 31547608

Showing the first eight; more decompositions exist.
