Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543926, here are decompositions:

13 + 31543913 = 31543926
19 + 31543907 = 31543926
23 + 31543903 = 31543926
53 + 31543873 = 31543926
67 + 31543859 = 31543926
79 + 31543847 = 31543926
83 + 31543843 = 31543926
97 + 31543829 = 31543926

Showing the first eight; more decompositions exist.
