Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458606, here are decompositions:

5 + 31458601 = 31458606
13 + 31458593 = 31458606
17 + 31458589 = 31458606
19 + 31458587 = 31458606
79 + 31458527 = 31458606
227 + 31458379 = 31458606
229 + 31458377 = 31458606
233 + 31458373 = 31458606

Showing the first eight; more decompositions exist.
