Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458796, here are decompositions:

107 + 31458689 = 31458796
269 + 31458527 = 31458796
359 + 31458437 = 31458796
419 + 31458377 = 31458796
557 + 31458239 = 31458796
599 + 31458197 = 31458796
683 + 31458113 = 31458796
797 + 31457999 = 31458796

Showing the first eight; more decompositions exist.
