Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572364, here are decompositions:

17 + 31572347 = 31572364
23 + 31572341 = 31572364
41 + 31572323 = 31572364
101 + 31572263 = 31572364
137 + 31572227 = 31572364
233 + 31572131 = 31572364
281 + 31572083 = 31572364
347 + 31572017 = 31572364

Showing the first eight; more decompositions exist.
