Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458410, here are decompositions:

7 + 31458403 = 31458410
31 + 31458379 = 31458410
37 + 31458373 = 31458410
79 + 31458331 = 31458410
223 + 31458187 = 31458410
241 + 31458169 = 31458410
349 + 31458061 = 31458410
397 + 31458013 = 31458410

Showing the first eight; more decompositions exist.
