Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456852, here are decompositions:

3 + 31456849 = 31456852
23 + 31456829 = 31456852
71 + 31456781 = 31456852
83 + 31456769 = 31456852
113 + 31456739 = 31456852
131 + 31456721 = 31456852
149 + 31456703 = 31456852
173 + 31456679 = 31456852

Showing the first eight; more decompositions exist.
