Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473184, here are decompositions:

11 + 31473173 = 31473184
23 + 31473161 = 31473184
101 + 31473083 = 31473184
107 + 31473077 = 31473184
257 + 31472927 = 31473184
293 + 31472891 = 31473184
317 + 31472867 = 31473184
461 + 31472723 = 31473184

Showing the first eight; more decompositions exist.
