Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462454, here are decompositions:

3 + 31462451 = 31462454
13 + 31462441 = 31462454
73 + 31462381 = 31462454
97 + 31462357 = 31462454
103 + 31462351 = 31462454
181 + 31462273 = 31462454
313 + 31462141 = 31462454
433 + 31462021 = 31462454

Showing the first eight; more decompositions exist.
