Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496428, here are decompositions:

11 + 31496417 = 31496428
59 + 31496369 = 31496428
107 + 31496321 = 31496428
167 + 31496261 = 31496428
401 + 31496027 = 31496428
449 + 31495979 = 31496428
479 + 31495949 = 31496428
569 + 31495859 = 31496428

Showing the first eight; more decompositions exist.
