Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454936, here are decompositions:

13 + 31454923 = 31454936
109 + 31454827 = 31454936
127 + 31454809 = 31454936
199 + 31454737 = 31454936
283 + 31454653 = 31454936
349 + 31454587 = 31454936
439 + 31454497 = 31454936
547 + 31454389 = 31454936

Showing the first eight; more decompositions exist.
