Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543286, here are decompositions:

13 + 31543273 = 31543286
43 + 31543243 = 31543286
67 + 31543219 = 31543286
79 + 31543207 = 31543286
277 + 31543009 = 31543286
337 + 31542949 = 31543286
349 + 31542937 = 31543286
409 + 31542877 = 31543286

Showing the first eight; more decompositions exist.
