Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504116, here are decompositions:

13 + 31504103 = 31504116
19 + 31504097 = 31504116
29 + 31504087 = 31504116
79 + 31504037 = 31504116
103 + 31504013 = 31504116
139 + 31503977 = 31504116
199 + 31503917 = 31504116
229 + 31503887 = 31504116

Showing the first eight; more decompositions exist.
