Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544376, here are decompositions:

5 + 31544371 = 31544376
13 + 31544363 = 31544376
29 + 31544347 = 31544376
53 + 31544323 = 31544376
79 + 31544297 = 31544376
163 + 31544213 = 31544376
197 + 31544179 = 31544376
223 + 31544153 = 31544376

Showing the first eight; more decompositions exist.
