Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570352, here are decompositions:

61 + 31570291 = 31570352
103 + 31570249 = 31570352
181 + 31570171 = 31570352
193 + 31570159 = 31570352
211 + 31570141 = 31570352
241 + 31570111 = 31570352
271 + 31570081 = 31570352
409 + 31569943 = 31570352

Showing the first eight; more decompositions exist.
