Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567514, here are decompositions:

3 + 31567511 = 31567514
103 + 31567411 = 31567514
283 + 31567231 = 31567514
541 + 31566973 = 31567514
547 + 31566967 = 31567514
613 + 31566901 = 31567514
751 + 31566763 = 31567514
883 + 31566631 = 31567514

Showing the first eight; more decompositions exist.
