Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567432, here are decompositions:

3 + 31567429 = 31567432
5 + 31567427 = 31567432
191 + 31567241 = 31567432
383 + 31567049 = 31567432
389 + 31567043 = 31567432
521 + 31566911 = 31567432
569 + 31566863 = 31567432
593 + 31566839 = 31567432

Showing the first eight; more decompositions exist.
