Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572322, here are decompositions:

59 + 31572263 = 31572322
101 + 31572221 = 31572322
179 + 31572143 = 31572322
191 + 31572131 = 31572322
239 + 31572083 = 31572322
263 + 31572059 = 31572322
281 + 31572041 = 31572322
293 + 31572029 = 31572322

Showing the first eight; more decompositions exist.
