Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496818, here are decompositions:

149 + 31496669 = 31496818
251 + 31496567 = 31496818
281 + 31496537 = 31496818
389 + 31496429 = 31496818
401 + 31496417 = 31496818
449 + 31496369 = 31496818
557 + 31496261 = 31496818
599 + 31496219 = 31496818

Showing the first eight; more decompositions exist.
