Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539852, here are decompositions:

13 + 31539839 = 31539852
31 + 31539821 = 31539852
89 + 31539763 = 31539852
139 + 31539713 = 31539852
181 + 31539671 = 31539852
191 + 31539661 = 31539852
193 + 31539659 = 31539852
269 + 31539583 = 31539852

Showing the first eight; more decompositions exist.
