Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598144, here are decompositions:

3 + 31598141 = 31598144
7 + 31598137 = 31598144
43 + 31598101 = 31598144
157 + 31597987 = 31598144
211 + 31597933 = 31598144
271 + 31597873 = 31598144
367 + 31597777 = 31598144
541 + 31597603 = 31598144

Showing the first eight; more decompositions exist.
