Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544346, here are decompositions:

23 + 31544323 = 31544346
139 + 31544207 = 31544346
157 + 31544189 = 31544346
167 + 31544179 = 31544346
179 + 31544167 = 31544346
193 + 31544153 = 31544346
257 + 31544089 = 31544346
269 + 31544077 = 31544346

Showing the first eight; more decompositions exist.
