Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473112, here are decompositions:

3 + 31473109 = 31473112
5 + 31473107 = 31473112
29 + 31473083 = 31473112
71 + 31473041 = 31473112
149 + 31472963 = 31473112
233 + 31472879 = 31473112
263 + 31472849 = 31473112
389 + 31472723 = 31473112

Showing the first eight; more decompositions exist.
