Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572054, here are decompositions:

5 + 31572049 = 31572054
13 + 31572041 = 31572054
37 + 31572017 = 31572054
47 + 31572007 = 31572054
61 + 31571993 = 31572054
71 + 31571983 = 31572054
97 + 31571957 = 31572054
167 + 31571887 = 31572054

Showing the first eight; more decompositions exist.
