Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476396, here are decompositions:

5 + 31476391 = 31476396
13 + 31476383 = 31476396
23 + 31476373 = 31476396
43 + 31476353 = 31476396
47 + 31476349 = 31476396
53 + 31476343 = 31476396
79 + 31476317 = 31476396
113 + 31476283 = 31476396

Showing the first eight; more decompositions exist.
