Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610384, here are decompositions:

31 + 31610353 = 31610384
67 + 31610317 = 31610384
97 + 31610287 = 31610384
241 + 31610143 = 31610384
271 + 31610113 = 31610384
277 + 31610107 = 31610384
373 + 31610011 = 31610384
523 + 31609861 = 31610384

Showing the first eight; more decompositions exist.
