Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484636, here are decompositions:

19 + 31484617 = 31484636
67 + 31484569 = 31484636
103 + 31484533 = 31484636
223 + 31484413 = 31484636
277 + 31484359 = 31484636
283 + 31484353 = 31484636
397 + 31484239 = 31484636
433 + 31484203 = 31484636

Showing the first eight; more decompositions exist.
