Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458626, here are decompositions:

19 + 31458607 = 31458626
37 + 31458589 = 31458626
139 + 31458487 = 31458626
223 + 31458403 = 31458626
349 + 31458277 = 31458626
439 + 31458187 = 31458626
457 + 31458169 = 31458626
613 + 31458013 = 31458626

Showing the first eight; more decompositions exist.
