Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607104, here are decompositions:

3 + 31607101 = 31607104
17 + 31607087 = 31607104
107 + 31606997 = 31607104
131 + 31606973 = 31607104
173 + 31606931 = 31607104
257 + 31606847 = 31607104
293 + 31606811 = 31607104
401 + 31606703 = 31607104

Showing the first eight; more decompositions exist.
