Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607394, here are decompositions:

31 + 31607363 = 31607394
37 + 31607357 = 31607394
53 + 31607341 = 31607394
67 + 31607327 = 31607394
97 + 31607297 = 31607394
101 + 31607293 = 31607394
103 + 31607291 = 31607394
113 + 31607281 = 31607394

Showing the first eight; more decompositions exist.
