Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523932, here are decompositions:

131 + 31523801 = 31523932
179 + 31523753 = 31523932
263 + 31523669 = 31523932
281 + 31523651 = 31523932
353 + 31523579 = 31523932
491 + 31523441 = 31523932
521 + 31523411 = 31523932
653 + 31523279 = 31523932

Showing the first eight; more decompositions exist.
