Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533930, here are decompositions:

7 + 31533923 = 31533930
11 + 31533919 = 31533930
19 + 31533911 = 31533930
59 + 31533871 = 31533930
83 + 31533847 = 31533930
97 + 31533833 = 31533930
101 + 31533829 = 31533930
107 + 31533823 = 31533930

Showing the first eight; more decompositions exist.
