Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598792, here are decompositions:

3 + 31598789 = 31598792
13 + 31598779 = 31598792
109 + 31598683 = 31598792
271 + 31598521 = 31598792
373 + 31598419 = 31598792
439 + 31598353 = 31598792
601 + 31598191 = 31598792
613 + 31598179 = 31598792

Showing the first eight; more decompositions exist.
