Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570292, here are decompositions:

3 + 31570289 = 31570292
31 + 31570261 = 31570292
43 + 31570249 = 31570292
73 + 31570219 = 31570292
151 + 31570141 = 31570292
181 + 31570111 = 31570292
211 + 31570081 = 31570292
349 + 31569943 = 31570292

Showing the first eight; more decompositions exist.
