Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596998, here are decompositions:

7 + 31596991 = 31596998
109 + 31596889 = 31596998
151 + 31596847 = 31596998
229 + 31596769 = 31596998
241 + 31596757 = 31596998
337 + 31596661 = 31596998
457 + 31596541 = 31596998
487 + 31596511 = 31596998

Showing the first eight; more decompositions exist.
