Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557322, here are decompositions:

29 + 31557293 = 31557322
191 + 31557131 = 31557322
311 + 31557011 = 31557322
383 + 31556939 = 31557322
509 + 31556813 = 31557322
683 + 31556639 = 31557322
821 + 31556501 = 31557322
941 + 31556381 = 31557322

Showing the first eight; more decompositions exist.
