Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610752, here are decompositions:

11 + 31610741 = 31610752
23 + 31610729 = 31610752
29 + 31610723 = 31610752
113 + 31610639 = 31610752
179 + 31610573 = 31610752
191 + 31610561 = 31610752
233 + 31610519 = 31610752
359 + 31610393 = 31610752

Showing the first eight; more decompositions exist.
