Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502932, here are decompositions:

5 + 31502927 = 31502932
233 + 31502699 = 31502932
443 + 31502489 = 31502932
449 + 31502483 = 31502932
491 + 31502441 = 31502932
569 + 31502363 = 31502932
599 + 31502333 = 31502932
653 + 31502279 = 31502932

Showing the first eight; more decompositions exist.
