Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472366, here are decompositions:

7 + 31472359 = 31472366
73 + 31472293 = 31472366
127 + 31472239 = 31472366
157 + 31472209 = 31472366
199 + 31472167 = 31472366
223 + 31472143 = 31472366
313 + 31472053 = 31472366
337 + 31472029 = 31472366

Showing the first eight; more decompositions exist.
