Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462974, here are decompositions:

5 + 31462969 = 31462974
41 + 31462933 = 31462974
43 + 31462931 = 31462974
73 + 31462901 = 31462974
97 + 31462877 = 31462974
163 + 31462811 = 31462974
167 + 31462807 = 31462974
181 + 31462793 = 31462974

Showing the first eight; more decompositions exist.
