Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502704, here are decompositions:

3 + 31502701 = 31502704
5 + 31502699 = 31502704
17 + 31502687 = 31502704
263 + 31502441 = 31502704
461 + 31502243 = 31502704
491 + 31502213 = 31502704
521 + 31502183 = 31502704
557 + 31502147 = 31502704

Showing the first eight; more decompositions exist.
