Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532494, here are decompositions:

5 + 31532489 = 31532494
17 + 31532477 = 31532494
233 + 31532261 = 31532494
353 + 31532141 = 31532494
431 + 31532063 = 31532494
491 + 31532003 = 31532494
563 + 31531931 = 31532494
677 + 31531817 = 31532494

Showing the first eight; more decompositions exist.
