Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462518, here are decompositions:

11 + 31462507 = 31462518
37 + 31462481 = 31462518
47 + 31462471 = 31462518
67 + 31462451 = 31462518
79 + 31462439 = 31462518
137 + 31462381 = 31462518
167 + 31462351 = 31462518
179 + 31462339 = 31462518

Showing the first eight; more decompositions exist.
