Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574934, here are decompositions:

7 + 31574927 = 31574934
23 + 31574911 = 31574934
43 + 31574891 = 31574934
47 + 31574887 = 31574934
71 + 31574863 = 31574934
73 + 31574861 = 31574934
113 + 31574821 = 31574934
211 + 31574723 = 31574934

Showing the first eight; more decompositions exist.
