Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473558, here are decompositions:

29 + 31473529 = 31473558
71 + 31473487 = 31473558
79 + 31473479 = 31473558
101 + 31473457 = 31473558
199 + 31473359 = 31473558
227 + 31473331 = 31473558
307 + 31473251 = 31473558
317 + 31473241 = 31473558

Showing the first eight; more decompositions exist.
