Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462560, here are decompositions:

7 + 31462553 = 31462560
13 + 31462547 = 31462560
29 + 31462531 = 31462560
53 + 31462507 = 31462560
79 + 31462481 = 31462560
89 + 31462471 = 31462560
109 + 31462451 = 31462560
127 + 31462433 = 31462560

Showing the first eight; more decompositions exist.
