Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473370, here are decompositions:

11 + 31473359 = 31473370
107 + 31473263 = 31473370
167 + 31473203 = 31473370
179 + 31473191 = 31473370
197 + 31473173 = 31473370
263 + 31473107 = 31473370
293 + 31473077 = 31473370
443 + 31472927 = 31473370

Showing the first eight; more decompositions exist.
