Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473466, here are decompositions:

29 + 31473437 = 31473466
53 + 31473413 = 31473466
107 + 31473359 = 31473466
257 + 31473209 = 31473466
263 + 31473203 = 31473466
293 + 31473173 = 31473466
359 + 31473107 = 31473466
383 + 31473083 = 31473466

Showing the first eight; more decompositions exist.
