Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598982, here are decompositions:

29 + 31598953 = 31598982
43 + 31598939 = 31598982
59 + 31598923 = 31598982
71 + 31598911 = 31598982
73 + 31598909 = 31598982
109 + 31598873 = 31598982
193 + 31598789 = 31598982
199 + 31598783 = 31598982

Showing the first eight; more decompositions exist.
