Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610356, here are decompositions:

3 + 31610353 = 31610356
17 + 31610339 = 31610356
23 + 31610333 = 31610356
263 + 31610093 = 31610356
293 + 31610063 = 31610356
317 + 31610039 = 31610356
347 + 31610009 = 31610356
383 + 31609973 = 31610356

Showing the first eight; more decompositions exist.
