Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534012, here are decompositions:

53 + 31533959 = 31534012
89 + 31533923 = 31534012
101 + 31533911 = 31534012
173 + 31533839 = 31534012
179 + 31533833 = 31534012
239 + 31533773 = 31534012
353 + 31533659 = 31534012
401 + 31533611 = 31534012

Showing the first eight; more decompositions exist.
