Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467600, here are decompositions:

7 + 31467593 = 31467600
11 + 31467589 = 31467600
13 + 31467587 = 31467600
29 + 31467571 = 31467600
41 + 31467559 = 31467600
61 + 31467539 = 31467600
67 + 31467533 = 31467600
97 + 31467503 = 31467600

Showing the first eight; more decompositions exist.
