Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567184, here are decompositions:

31 + 31567153 = 31567184
97 + 31567087 = 31567184
211 + 31566973 = 31567184
283 + 31566901 = 31567184
367 + 31566817 = 31567184
421 + 31566763 = 31567184
643 + 31566541 = 31567184
661 + 31566523 = 31567184

Showing the first eight; more decompositions exist.
