Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458494, here are decompositions:

7 + 31458487 = 31458494
13 + 31458481 = 31458494
43 + 31458451 = 31458494
163 + 31458331 = 31458494
307 + 31458187 = 31458494
433 + 31458061 = 31458494
673 + 31457821 = 31458494
751 + 31457743 = 31458494

Showing the first eight; more decompositions exist.
