Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538852, here are decompositions:

73 + 31538779 = 31538852
109 + 31538743 = 31538852
139 + 31538713 = 31538852
181 + 31538671 = 31538852
199 + 31538653 = 31538852
211 + 31538641 = 31538852
223 + 31538629 = 31538852
229 + 31538623 = 31538852

Showing the first eight; more decompositions exist.
