Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567032, here are decompositions:

53 + 31566979 = 31567032
59 + 31566973 = 31567032
113 + 31566919 = 31567032
131 + 31566901 = 31567032
193 + 31566839 = 31567032
229 + 31566803 = 31567032
239 + 31566793 = 31567032
269 + 31566763 = 31567032

Showing the first eight; more decompositions exist.
