Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489104, here are decompositions:

7 + 31489097 = 31489104
13 + 31489091 = 31489104
41 + 31489063 = 31489104
61 + 31489043 = 31489104
67 + 31489037 = 31489104
113 + 31488991 = 31489104
173 + 31488931 = 31489104
193 + 31488911 = 31489104

Showing the first eight; more decompositions exist.
