Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525914, here are decompositions:

5 + 31525909 = 31525914
11 + 31525903 = 31525914
23 + 31525891 = 31525914
73 + 31525841 = 31525914
97 + 31525817 = 31525914
103 + 31525811 = 31525914
127 + 31525787 = 31525914
131 + 31525783 = 31525914

Showing the first eight; more decompositions exist.
