Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458704, here are decompositions:

3 + 31458701 = 31458704
7 + 31458697 = 31458704
37 + 31458667 = 31458704
61 + 31458643 = 31458704
73 + 31458631 = 31458704
97 + 31458607 = 31458704
103 + 31458601 = 31458704
163 + 31458541 = 31458704

Showing the first eight; more decompositions exist.
