Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477236, here are decompositions:

23 + 31477213 = 31477236
29 + 31477207 = 31477236
73 + 31477163 = 31477236
137 + 31477099 = 31477236
157 + 31477079 = 31477236
173 + 31477063 = 31477236
179 + 31477057 = 31477236
277 + 31476959 = 31477236

Showing the first eight; more decompositions exist.
