Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462548, here are decompositions:

17 + 31462531 = 31462548
41 + 31462507 = 31462548
67 + 31462481 = 31462548
97 + 31462451 = 31462548
107 + 31462441 = 31462548
109 + 31462439 = 31462548
167 + 31462381 = 31462548
191 + 31462357 = 31462548

Showing the first eight; more decompositions exist.
