Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504098, here are decompositions:

11 + 31504087 = 31504098
47 + 31504051 = 31504098
61 + 31504037 = 31504098
127 + 31503971 = 31504098
137 + 31503961 = 31504098
167 + 31503931 = 31504098
181 + 31503917 = 31504098
211 + 31503887 = 31504098

Showing the first eight; more decompositions exist.
