Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567946, here are decompositions:

97 + 31567849 = 31567946
127 + 31567819 = 31567946
229 + 31567717 = 31567946
433 + 31567513 = 31567946
577 + 31567369 = 31567946
727 + 31567219 = 31567946
733 + 31567213 = 31567946
859 + 31567087 = 31567946

Showing the first eight; more decompositions exist.
