Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474088, here are decompositions:

31 + 31474057 = 31474088
97 + 31473991 = 31474088
157 + 31473931 = 31474088
181 + 31473907 = 31474088
241 + 31473847 = 31474088
277 + 31473811 = 31474088
307 + 31473781 = 31474088
601 + 31473487 = 31474088

Showing the first eight; more decompositions exist.
