Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496974, here are decompositions:

11 + 31496963 = 31496974
17 + 31496957 = 31496974
53 + 31496921 = 31496974
101 + 31496873 = 31496974
191 + 31496783 = 31496974
233 + 31496741 = 31496974
281 + 31496693 = 31496974
401 + 31496573 = 31496974

Showing the first eight; more decompositions exist.
