Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493366, here are decompositions:

13 + 31493353 = 31493366
19 + 31493347 = 31493366
43 + 31493323 = 31493366
283 + 31493083 = 31493366
313 + 31493053 = 31493366
337 + 31493029 = 31493366
349 + 31493017 = 31493366
433 + 31492933 = 31493366

Showing the first eight; more decompositions exist.
