Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567814, here are decompositions:

73 + 31567741 = 31567814
97 + 31567717 = 31567814
127 + 31567687 = 31567814
193 + 31567621 = 31567814
211 + 31567603 = 31567814
547 + 31567267 = 31567814
601 + 31567213 = 31567814
661 + 31567153 = 31567814

Showing the first eight; more decompositions exist.
