Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570476, here are decompositions:

17 + 31570459 = 31570476
29 + 31570447 = 31570476
79 + 31570397 = 31570476
97 + 31570379 = 31570476
103 + 31570373 = 31570476
139 + 31570337 = 31570476
163 + 31570313 = 31570476
173 + 31570303 = 31570476

Showing the first eight; more decompositions exist.
