Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462908, here are decompositions:

7 + 31462901 = 31462908
11 + 31462897 = 31462908
19 + 31462889 = 31462908
31 + 31462877 = 31462908
97 + 31462811 = 31462908
101 + 31462807 = 31462908
137 + 31462771 = 31462908
149 + 31462759 = 31462908

Showing the first eight; more decompositions exist.
