Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458214, here are decompositions:

17 + 31458197 = 31458214
23 + 31458191 = 31458214
41 + 31458173 = 31458214
83 + 31458131 = 31458214
101 + 31458113 = 31458214
131 + 31458083 = 31458214
311 + 31457903 = 31458214
353 + 31457861 = 31458214

Showing the first eight; more decompositions exist.
