Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569036, here are decompositions:

67 + 31568969 = 31569036
97 + 31568939 = 31569036
127 + 31568909 = 31569036
139 + 31568897 = 31569036
157 + 31568879 = 31569036
167 + 31568869 = 31569036
193 + 31568843 = 31569036
197 + 31568839 = 31569036

Showing the first eight; more decompositions exist.
