Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610686, here are decompositions:

47 + 31610639 = 31610686
113 + 31610573 = 31610686
167 + 31610519 = 31610686
293 + 31610393 = 31610686
347 + 31610339 = 31610686
353 + 31610333 = 31610686
449 + 31610237 = 31610686
593 + 31610093 = 31610686

Showing the first eight; more decompositions exist.
