Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576596, here are decompositions:

13 + 31576583 = 31576596
17 + 31576579 = 31576596
47 + 31576549 = 31576596
67 + 31576529 = 31576596
113 + 31576483 = 31576596
137 + 31576459 = 31576596
157 + 31576439 = 31576596
179 + 31576417 = 31576596

Showing the first eight; more decompositions exist.
