Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544340, here are decompositions:

17 + 31544323 = 31544340
29 + 31544311 = 31544340
43 + 31544297 = 31544340
59 + 31544281 = 31544340
127 + 31544213 = 31544340
151 + 31544189 = 31544340
173 + 31544167 = 31544340
241 + 31544099 = 31544340

Showing the first eight; more decompositions exist.
