Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502794, here are decompositions:

17 + 31502777 = 31502794
107 + 31502687 = 31502794
233 + 31502561 = 31502794
311 + 31502483 = 31502794
353 + 31502441 = 31502794
431 + 31502363 = 31502794
461 + 31502333 = 31502794
647 + 31502147 = 31502794

Showing the first eight; more decompositions exist.
