Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558214, here are decompositions:

3 + 31558211 = 31558214
7 + 31558207 = 31558214
67 + 31558147 = 31558214
151 + 31558063 = 31558214
157 + 31558057 = 31558214
277 + 31557937 = 31558214
283 + 31557931 = 31558214
577 + 31557637 = 31558214

Showing the first eight; more decompositions exist.
