Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472460, here are decompositions:

11 + 31472449 = 31472460
23 + 31472437 = 31472460
101 + 31472359 = 31472460
109 + 31472351 = 31472460
167 + 31472293 = 31472460
199 + 31472261 = 31472460
251 + 31472209 = 31472460
269 + 31472191 = 31472460

Showing the first eight; more decompositions exist.
