Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572344, here are decompositions:

3 + 31572341 = 31572344
43 + 31572301 = 31572344
61 + 31572283 = 31572344
103 + 31572241 = 31572344
163 + 31572181 = 31572344
211 + 31572133 = 31572344
337 + 31572007 = 31572344
457 + 31571887 = 31572344

Showing the first eight; more decompositions exist.
