Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567124, here are decompositions:

37 + 31567087 = 31567124
151 + 31566973 = 31567124
157 + 31566967 = 31567124
223 + 31566901 = 31567124
307 + 31566817 = 31567124
331 + 31566793 = 31567124
577 + 31566547 = 31567124
601 + 31566523 = 31567124

Showing the first eight; more decompositions exist.
