Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598288, here are decompositions:

61 + 31598227 = 31598288
97 + 31598191 = 31598288
109 + 31598179 = 31598288
151 + 31598137 = 31598288
277 + 31598011 = 31598288
409 + 31597879 = 31598288
487 + 31597801 = 31598288
571 + 31597717 = 31598288

Showing the first eight; more decompositions exist.
