Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474298, here are decompositions:

7 + 31474291 = 31474298
127 + 31474171 = 31474298
157 + 31474141 = 31474298
241 + 31474057 = 31474298
307 + 31473991 = 31474298
367 + 31473931 = 31474298
397 + 31473901 = 31474298
487 + 31473811 = 31474298

Showing the first eight; more decompositions exist.
