Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473418, here are decompositions:

5 + 31473413 = 31473418
59 + 31473359 = 31473418
167 + 31473251 = 31473418
227 + 31473191 = 31473418
257 + 31473161 = 31473418
311 + 31473107 = 31473418
491 + 31472927 = 31473418
569 + 31472849 = 31473418

Showing the first eight; more decompositions exist.
