Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503766, here are decompositions:

17 + 31503749 = 31503766
53 + 31503713 = 31503766
197 + 31503569 = 31503766
257 + 31503509 = 31503766
443 + 31503323 = 31503766
557 + 31503209 = 31503766
563 + 31503203 = 31503766
587 + 31503179 = 31503766

Showing the first eight; more decompositions exist.
