Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504110, here are decompositions:

7 + 31504103 = 31504110
13 + 31504097 = 31504110
23 + 31504087 = 31504110
59 + 31504051 = 31504110
73 + 31504037 = 31504110
97 + 31504013 = 31504110
137 + 31503973 = 31504110
139 + 31503971 = 31504110

Showing the first eight; more decompositions exist.
