Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610680, here are decompositions:

41 + 31610639 = 31610680
107 + 31610573 = 31610680
317 + 31610363 = 31610680
347 + 31610333 = 31610680
389 + 31610291 = 31610680
401 + 31610279 = 31610680
443 + 31610237 = 31610680
449 + 31610231 = 31610680

Showing the first eight; more decompositions exist.
