Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563106, here are decompositions:

17 + 31563089 = 31563106
257 + 31562849 = 31563106
479 + 31562627 = 31563106
503 + 31562603 = 31563106
563 + 31562543 = 31563106
587 + 31562519 = 31563106
677 + 31562429 = 31563106
683 + 31562423 = 31563106

Showing the first eight; more decompositions exist.
