Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538476, here are decompositions:

3 + 31538473 = 31538476
149 + 31538327 = 31538476
269 + 31538207 = 31538476
443 + 31538033 = 31538476
479 + 31537997 = 31538476
587 + 31537889 = 31538476
617 + 31537859 = 31538476
653 + 31537823 = 31538476

Showing the first eight; more decompositions exist.
