Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534172, here are decompositions:

3 + 31534169 = 31534172
31 + 31534141 = 31534172
139 + 31534033 = 31534172
193 + 31533979 = 31534172
223 + 31533949 = 31534172
349 + 31533823 = 31534172
409 + 31533763 = 31534172
541 + 31533631 = 31534172

Showing the first eight; more decompositions exist.
