Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546920, here are decompositions:

7 + 31546913 = 31546920
11 + 31546909 = 31546920
29 + 31546891 = 31546920
59 + 31546861 = 31546920
73 + 31546847 = 31546920
89 + 31546831 = 31546920
103 + 31546817 = 31546920
107 + 31546813 = 31546920

Showing the first eight; more decompositions exist.
