Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463206, here are decompositions:

3 + 31463203 = 31463206
59 + 31463147 = 31463206
83 + 31463123 = 31463206
107 + 31463099 = 31463206
227 + 31462979 = 31463206
317 + 31462889 = 31463206
449 + 31462757 = 31463206
557 + 31462649 = 31463206

Showing the first eight; more decompositions exist.
