Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520464, here are decompositions:

11 + 31520453 = 31520464
47 + 31520417 = 31520464
71 + 31520393 = 31520464
263 + 31520201 = 31520464
293 + 31520171 = 31520464
347 + 31520117 = 31520464
587 + 31519877 = 31520464
641 + 31519823 = 31520464

Showing the first eight; more decompositions exist.
