Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497824, here are decompositions:

67 + 31497757 = 31497824
73 + 31497751 = 31497824
97 + 31497727 = 31497824
103 + 31497721 = 31497824
151 + 31497673 = 31497824
157 + 31497667 = 31497824
223 + 31497601 = 31497824
277 + 31497547 = 31497824

Showing the first eight; more decompositions exist.
