Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456074, here are decompositions:

7 + 31456067 = 31456074
53 + 31456021 = 31456074
61 + 31456013 = 31456074
71 + 31456003 = 31456074
113 + 31455961 = 31456074
127 + 31455947 = 31456074
173 + 31455901 = 31456074
197 + 31455877 = 31456074

Showing the first eight; more decompositions exist.
