Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452882, here are decompositions:

23 + 31452859 = 31452882
31 + 31452851 = 31452882
53 + 31452829 = 31452882
79 + 31452803 = 31452882
89 + 31452793 = 31452882
113 + 31452769 = 31452882
151 + 31452731 = 31452882
163 + 31452719 = 31452882

Showing the first eight; more decompositions exist.
