Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589454, here are decompositions:

31 + 31589423 = 31589454
47 + 31589407 = 31589454
53 + 31589401 = 31589454
101 + 31589353 = 31589454
137 + 31589317 = 31589454
151 + 31589303 = 31589454
157 + 31589297 = 31589454
163 + 31589291 = 31589454

Showing the first eight; more decompositions exist.
