Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598504, here are decompositions:

103 + 31598401 = 31598504
127 + 31598377 = 31598504
151 + 31598353 = 31598504
277 + 31598227 = 31598504
313 + 31598191 = 31598504
367 + 31598137 = 31598504
571 + 31597933 = 31598504
577 + 31597927 = 31598504

Showing the first eight; more decompositions exist.
