Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458662, here are decompositions:

19 + 31458643 = 31458662
31 + 31458631 = 31458662
61 + 31458601 = 31458662
73 + 31458589 = 31458662
181 + 31458481 = 31458662
211 + 31458451 = 31458662
283 + 31458379 = 31458662
331 + 31458331 = 31458662

Showing the first eight; more decompositions exist.
