Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547576, here are decompositions:

19 + 31547557 = 31547576
37 + 31547539 = 31547576
97 + 31547479 = 31547576
127 + 31547449 = 31547576
163 + 31547413 = 31547576
367 + 31547209 = 31547576
373 + 31547203 = 31547576
433 + 31547143 = 31547576

Showing the first eight; more decompositions exist.
