Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567598, here are decompositions:

229 + 31567369 = 31567598
331 + 31567267 = 31567598
367 + 31567231 = 31567598
379 + 31567219 = 31567598
619 + 31566979 = 31567598
631 + 31566967 = 31567598
967 + 31566631 = 31567598
1009 + 31566589 = 31567598

Showing the first eight; more decompositions exist.
