Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504636, here are decompositions:

17 + 31504619 = 31504636
29 + 31504607 = 31504636
89 + 31504547 = 31504636
197 + 31504439 = 31504636
263 + 31504373 = 31504636
269 + 31504367 = 31504636
503 + 31504133 = 31504636
509 + 31504127 = 31504636

Showing the first eight; more decompositions exist.
