Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544366, here are decompositions:

3 + 31544363 = 31544366
19 + 31544347 = 31544366
43 + 31544323 = 31544366
199 + 31544167 = 31544366
277 + 31544089 = 31544366
313 + 31544053 = 31544366
379 + 31543987 = 31544366
439 + 31543927 = 31544366

Showing the first eight; more decompositions exist.
