Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567748, here are decompositions:

7 + 31567741 = 31567748
19 + 31567729 = 31567748
31 + 31567717 = 31567748
61 + 31567687 = 31567748
67 + 31567681 = 31567748
127 + 31567621 = 31567748
337 + 31567411 = 31567748
379 + 31567369 = 31567748

Showing the first eight; more decompositions exist.
