Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544418, here are decompositions:

47 + 31544371 = 31544418
71 + 31544347 = 31544418
107 + 31544311 = 31544418
137 + 31544281 = 31544418
197 + 31544221 = 31544418
211 + 31544207 = 31544418
229 + 31544189 = 31544418
239 + 31544179 = 31544418

Showing the first eight; more decompositions exist.
