Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458714, here are decompositions:

5 + 31458709 = 31458714
11 + 31458703 = 31458714
13 + 31458701 = 31458714
17 + 31458697 = 31458714
47 + 31458667 = 31458714
71 + 31458643 = 31458714
83 + 31458631 = 31458714
107 + 31458607 = 31458714

Showing the first eight; more decompositions exist.
