Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496920, here are decompositions:

3 + 31496917 = 31496920
47 + 31496873 = 31496920
101 + 31496819 = 31496920
137 + 31496783 = 31496920
179 + 31496741 = 31496920
227 + 31496693 = 31496920
251 + 31496669 = 31496920
347 + 31496573 = 31496920

Showing the first eight; more decompositions exist.
