Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504196, here are decompositions:

7 + 31504189 = 31504196
13 + 31504183 = 31504196
67 + 31504129 = 31504196
109 + 31504087 = 31504196
223 + 31503973 = 31504196
313 + 31503883 = 31504196
349 + 31503847 = 31504196
397 + 31503799 = 31504196

Showing the first eight; more decompositions exist.
