Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547162, here are decompositions:

19 + 31547143 = 31547162
61 + 31547101 = 31547162
181 + 31546981 = 31547162
193 + 31546969 = 31547162
271 + 31546891 = 31547162
331 + 31546831 = 31547162
349 + 31546813 = 31547162
373 + 31546789 = 31547162

Showing the first eight; more decompositions exist.
