Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599398, here are decompositions:

139 + 31599259 = 31599398
151 + 31599247 = 31599398
241 + 31599157 = 31599398
409 + 31598989 = 31599398
487 + 31598911 = 31599398
541 + 31598857 = 31599398
619 + 31598779 = 31599398
751 + 31598647 = 31599398

Showing the first eight; more decompositions exist.
