Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496574, here are decompositions:

7 + 31496567 = 31496574
23 + 31496551 = 31496574
37 + 31496537 = 31496574
157 + 31496417 = 31496574
257 + 31496317 = 31496574
281 + 31496293 = 31496574
311 + 31496263 = 31496574
313 + 31496261 = 31496574

Showing the first eight; more decompositions exist.
