Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520434, here are decompositions:

17 + 31520417 = 31520434
41 + 31520393 = 31520434
47 + 31520387 = 31520434
191 + 31520243 = 31520434
233 + 31520201 = 31520434
263 + 31520171 = 31520434
293 + 31520141 = 31520434
317 + 31520117 = 31520434

Showing the first eight; more decompositions exist.
