Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447326, here are decompositions:

59 + 31447267 = 31447326
73 + 31447253 = 31447326
109 + 31447217 = 31447326
137 + 31447189 = 31447326
193 + 31447133 = 31447326
223 + 31447103 = 31447326
227 + 31447099 = 31447326
257 + 31447069 = 31447326

Showing the first eight; more decompositions exist.
