Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567106, here are decompositions:

19 + 31567087 = 31567106
127 + 31566979 = 31567106
139 + 31566967 = 31567106
313 + 31566793 = 31567106
397 + 31566709 = 31567106
547 + 31566559 = 31567106
619 + 31566487 = 31567106
709 + 31566397 = 31567106

Showing the first eight; more decompositions exist.
