Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547112, here are decompositions:

11 + 31547101 = 31547112
19 + 31547093 = 31547112
73 + 31547039 = 31547112
109 + 31547003 = 31547112
131 + 31546981 = 31547112
199 + 31546913 = 31547112
251 + 31546861 = 31547112
269 + 31546843 = 31547112

Showing the first eight; more decompositions exist.
