Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571302, here are decompositions:

83 + 31571219 = 31571302
89 + 31571213 = 31571302
101 + 31571201 = 31571302
239 + 31571063 = 31571302
263 + 31571039 = 31571302
281 + 31571021 = 31571302
293 + 31571009 = 31571302
353 + 31570949 = 31571302

Showing the first eight; more decompositions exist.
