Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567634, here are decompositions:

13 + 31567621 = 31567634
31 + 31567603 = 31567634
223 + 31567411 = 31567634
337 + 31567297 = 31567634
367 + 31567267 = 31567634
421 + 31567213 = 31567634
547 + 31567087 = 31567634
661 + 31566973 = 31567634

Showing the first eight; more decompositions exist.
