Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572034, here are decompositions:

5 + 31572029 = 31572034
17 + 31572017 = 31572034
41 + 31571993 = 31572034
71 + 31571963 = 31572034
167 + 31571867 = 31572034
257 + 31571777 = 31572034
383 + 31571651 = 31572034
443 + 31571591 = 31572034

Showing the first eight; more decompositions exist.
