Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536322, here are decompositions:

29 + 31536293 = 31536322
269 + 31536053 = 31536322
383 + 31535939 = 31536322
443 + 31535879 = 31536322
491 + 31535831 = 31536322
569 + 31535753 = 31536322
641 + 31535681 = 31536322
683 + 31535639 = 31536322

Showing the first eight; more decompositions exist.
