Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504104, here are decompositions:

7 + 31504097 = 31504104
17 + 31504087 = 31504104
53 + 31504051 = 31504104
67 + 31504037 = 31504104
127 + 31503977 = 31504104
131 + 31503973 = 31504104
173 + 31503931 = 31504104
193 + 31503911 = 31504104

Showing the first eight; more decompositions exist.
