Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623232, here are decompositions:

23 + 31623209 = 31623232
59 + 31623173 = 31623232
191 + 31623041 = 31623232
281 + 31622951 = 31623232
293 + 31622939 = 31623232
491 + 31622741 = 31623232
503 + 31622729 = 31623232
569 + 31622663 = 31623232

Showing the first eight; more decompositions exist.
