Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539052, here are decompositions:

5 + 31539047 = 31539052
101 + 31538951 = 31539052
263 + 31538789 = 31539052
359 + 31538693 = 31539052
491 + 31538561 = 31539052
563 + 31538489 = 31539052
641 + 31538411 = 31539052
719 + 31538333 = 31539052

Showing the first eight; more decompositions exist.
