Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503634, here are decompositions:

3 + 31503631 = 31503634
191 + 31503443 = 31503634
293 + 31503341 = 31503634
311 + 31503323 = 31503634
431 + 31503203 = 31503634
467 + 31503167 = 31503634
641 + 31502993 = 31503634
857 + 31502777 = 31503634

Showing the first eight; more decompositions exist.
