Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577796, here are decompositions:

13 + 31577783 = 31577796
17 + 31577779 = 31577796
23 + 31577773 = 31577796
67 + 31577729 = 31577796
79 + 31577717 = 31577796
127 + 31577669 = 31577796
137 + 31577659 = 31577796
139 + 31577657 = 31577796

Showing the first eight; more decompositions exist.
