Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547874, here are decompositions:

13 + 31547861 = 31547874
23 + 31547851 = 31547874
37 + 31547837 = 31547874
41 + 31547833 = 31547874
167 + 31547707 = 31547874
173 + 31547701 = 31547874
181 + 31547693 = 31547874
191 + 31547683 = 31547874

Showing the first eight; more decompositions exist.
