Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547174, here are decompositions:

13 + 31547161 = 31547174
31 + 31547143 = 31547174
73 + 31547101 = 31547174
97 + 31547077 = 31547174
193 + 31546981 = 31547174
283 + 31546891 = 31547174
313 + 31546861 = 31547174
331 + 31546843 = 31547174

Showing the first eight; more decompositions exist.
