Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610584, here are decompositions:

3 + 31610581 = 31610584
11 + 31610573 = 31610584
23 + 31610561 = 31610584
191 + 31610393 = 31610584
251 + 31610333 = 31610584
293 + 31610291 = 31610584
347 + 31610237 = 31610584
353 + 31610231 = 31610584

Showing the first eight; more decompositions exist.
