Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475636, here are decompositions:

13 + 31475623 = 31475636
37 + 31475599 = 31475636
193 + 31475443 = 31475636
229 + 31475407 = 31475636
349 + 31475287 = 31475636
547 + 31475089 = 31475636
607 + 31475029 = 31475636
769 + 31474867 = 31475636

Showing the first eight; more decompositions exist.
