Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604196, here are decompositions:

5 + 31604191 = 31604196
7 + 31604189 = 31604196
59 + 31604137 = 31604196
67 + 31604129 = 31604196
97 + 31604099 = 31604196
139 + 31604057 = 31604196
163 + 31604033 = 31604196
263 + 31603933 = 31604196

Showing the first eight; more decompositions exist.
