Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503484, here are decompositions:

41 + 31503443 = 31503484
281 + 31503203 = 31503484
317 + 31503167 = 31503484
431 + 31503053 = 31503484
491 + 31502993 = 31503484
521 + 31502963 = 31503484
557 + 31502927 = 31503484
587 + 31502897 = 31503484

Showing the first eight; more decompositions exist.
