Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475936, here are decompositions:

7 + 31475929 = 31475936
109 + 31475827 = 31475936
139 + 31475797 = 31475936
157 + 31475779 = 31475936
223 + 31475713 = 31475936
313 + 31475623 = 31475936
337 + 31475599 = 31475936
619 + 31475317 = 31475936

Showing the first eight; more decompositions exist.
