Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567098, here are decompositions:

7 + 31567091 = 31567098
11 + 31567087 = 31567098
131 + 31566967 = 31567098
179 + 31566919 = 31567098
197 + 31566901 = 31567098
271 + 31566827 = 31567098
281 + 31566817 = 31567098
349 + 31566749 = 31567098

Showing the first eight; more decompositions exist.
