Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472608, here are decompositions:

17 + 31472591 = 31472608
71 + 31472537 = 31472608
107 + 31472501 = 31472608
257 + 31472351 = 31472608
269 + 31472339 = 31472608
317 + 31472291 = 31472608
347 + 31472261 = 31472608
449 + 31472159 = 31472608

Showing the first eight; more decompositions exist.
