Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544514, here are decompositions:

5 + 31544509 = 31544514
97 + 31544417 = 31544514
151 + 31544363 = 31544514
167 + 31544347 = 31544514
191 + 31544323 = 31544514
233 + 31544281 = 31544514
293 + 31544221 = 31544514
307 + 31544207 = 31544514

Showing the first eight; more decompositions exist.
