Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472600, here are decompositions:

13 + 31472587 = 31472600
151 + 31472449 = 31472600
163 + 31472437 = 31472600
241 + 31472359 = 31472600
307 + 31472293 = 31472600
409 + 31472191 = 31472600
421 + 31472179 = 31472600
433 + 31472167 = 31472600

Showing the first eight; more decompositions exist.
