Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458674, here are decompositions:

7 + 31458667 = 31458674
31 + 31458643 = 31458674
43 + 31458631 = 31458674
67 + 31458607 = 31458674
73 + 31458601 = 31458674
193 + 31458481 = 31458674
223 + 31458451 = 31458674
271 + 31458403 = 31458674

Showing the first eight; more decompositions exist.
