Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458696, here are decompositions:

7 + 31458689 = 31458696
29 + 31458667 = 31458696
53 + 31458643 = 31458696
89 + 31458607 = 31458696
103 + 31458593 = 31458696
107 + 31458589 = 31458696
109 + 31458587 = 31458696
277 + 31458419 = 31458696

Showing the first eight; more decompositions exist.
