Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598402, here are decompositions:

103 + 31598299 = 31598402
163 + 31598239 = 31598402
211 + 31598191 = 31598402
223 + 31598179 = 31598402
373 + 31598029 = 31598402
523 + 31597879 = 31598402
601 + 31597801 = 31598402
673 + 31597729 = 31598402

Showing the first eight; more decompositions exist.
