Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547526, here are decompositions:

7 + 31547519 = 31547526
19 + 31547507 = 31547526
37 + 31547489 = 31547526
47 + 31547479 = 31547526
67 + 31547459 = 31547526
113 + 31547413 = 31547526
223 + 31547303 = 31547526
229 + 31547297 = 31547526

Showing the first eight; more decompositions exist.
