Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503826, here are decompositions:

17 + 31503809 = 31503826
47 + 31503779 = 31503826
113 + 31503713 = 31503826
257 + 31503569 = 31503826
269 + 31503557 = 31503826
317 + 31503509 = 31503826
383 + 31503443 = 31503826
503 + 31503323 = 31503826

Showing the first eight; more decompositions exist.
