Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462854, here are decompositions:

23 + 31462831 = 31462854
43 + 31462811 = 31462854
47 + 31462807 = 31462854
61 + 31462793 = 31462854
83 + 31462771 = 31462854
97 + 31462757 = 31462854
103 + 31462751 = 31462854
107 + 31462747 = 31462854

Showing the first eight; more decompositions exist.
