Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473388, here are decompositions:

29 + 31473359 = 31473388
137 + 31473251 = 31473388
179 + 31473209 = 31473388
197 + 31473191 = 31473388
227 + 31473161 = 31473388
281 + 31473107 = 31473388
311 + 31473077 = 31473388
347 + 31473041 = 31473388

Showing the first eight; more decompositions exist.
