Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460946, here are decompositions:

17 + 31460929 = 31460946
19 + 31460927 = 31460946
29 + 31460917 = 31460946
67 + 31460879 = 31460946
73 + 31460873 = 31460946
107 + 31460839 = 31460946
109 + 31460837 = 31460946
113 + 31460833 = 31460946

Showing the first eight; more decompositions exist.
