Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542852, here are decompositions:

23 + 31542829 = 31542852
41 + 31542811 = 31542852
43 + 31542809 = 31542852
53 + 31542799 = 31542852
149 + 31542703 = 31542852
193 + 31542659 = 31542852
239 + 31542613 = 31542852
293 + 31542559 = 31542852

Showing the first eight; more decompositions exist.
