Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473226, here are decompositions:

17 + 31473209 = 31473226
23 + 31473203 = 31473226
53 + 31473173 = 31473226
149 + 31473077 = 31473226
263 + 31472963 = 31473226
347 + 31472879 = 31473226
359 + 31472867 = 31473226
419 + 31472807 = 31473226

Showing the first eight; more decompositions exist.
