Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488652, here are decompositions:

5 + 31488647 = 31488652
89 + 31488563 = 31488652
281 + 31488371 = 31488652
353 + 31488299 = 31488652
359 + 31488293 = 31488652
449 + 31488203 = 31488652
491 + 31488161 = 31488652
563 + 31488089 = 31488652

Showing the first eight; more decompositions exist.
