Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598996, here are decompositions:

7 + 31598989 = 31598996
43 + 31598953 = 31598996
73 + 31598923 = 31598996
109 + 31598887 = 31598996
139 + 31598857 = 31598996
157 + 31598839 = 31598996
313 + 31598683 = 31598996
349 + 31598647 = 31598996

Showing the first eight; more decompositions exist.
