Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544544, here are decompositions:

11 + 31544533 = 31544544
13 + 31544531 = 31544544
127 + 31544417 = 31544544
151 + 31544393 = 31544544
173 + 31544371 = 31544544
181 + 31544363 = 31544544
197 + 31544347 = 31544544
233 + 31544311 = 31544544

Showing the first eight; more decompositions exist.
