Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596752, here are decompositions:

3 + 31596749 = 31596752
43 + 31596709 = 31596752
73 + 31596679 = 31596752
79 + 31596673 = 31596752
139 + 31596613 = 31596752
181 + 31596571 = 31596752
199 + 31596553 = 31596752
211 + 31596541 = 31596752

Showing the first eight; more decompositions exist.
