Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460856, here are decompositions:

5 + 31460851 = 31460856
17 + 31460839 = 31460856
19 + 31460837 = 31460856
23 + 31460833 = 31460856
47 + 31460809 = 31460856
73 + 31460783 = 31460856
113 + 31460743 = 31460856
127 + 31460729 = 31460856

Showing the first eight; more decompositions exist.
