Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557324, here are decompositions:

31 + 31557293 = 31557324
41 + 31557283 = 31557324
47 + 31557277 = 31557324
83 + 31557241 = 31557324
107 + 31557217 = 31557324
131 + 31557193 = 31557324
137 + 31557187 = 31557324
163 + 31557161 = 31557324

Showing the first eight; more decompositions exist.
