Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496452, here are decompositions:

3 + 31496449 = 31496452
11 + 31496441 = 31496452
23 + 31496429 = 31496452
83 + 31496369 = 31496452
131 + 31496321 = 31496452
191 + 31496261 = 31496452
233 + 31496219 = 31496452
311 + 31496141 = 31496452

Showing the first eight; more decompositions exist.
