Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598906, here are decompositions:

19 + 31598887 = 31598906
43 + 31598863 = 31598906
67 + 31598839 = 31598906
127 + 31598779 = 31598906
223 + 31598683 = 31598906
457 + 31598449 = 31598906
487 + 31598419 = 31598906
607 + 31598299 = 31598906

Showing the first eight; more decompositions exist.
