Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544368, here are decompositions:

5 + 31544363 = 31544368
71 + 31544297 = 31544368
179 + 31544189 = 31544368
197 + 31544171 = 31544368
269 + 31544099 = 31544368
311 + 31544057 = 31544368
347 + 31544021 = 31544368
389 + 31543979 = 31544368

Showing the first eight; more decompositions exist.
