Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473436, here are decompositions:

23 + 31473413 = 31473436
173 + 31473263 = 31473436
227 + 31473209 = 31473436
233 + 31473203 = 31473436
263 + 31473173 = 31473436
353 + 31473083 = 31473436
359 + 31473077 = 31473436
509 + 31472927 = 31473436

Showing the first eight; more decompositions exist.
