Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547508, here are decompositions:

19 + 31547489 = 31547508
29 + 31547479 = 31547508
37 + 31547471 = 31547508
59 + 31547449 = 31547508
67 + 31547441 = 31547508
151 + 31547357 = 31547508
191 + 31547317 = 31547508
211 + 31547297 = 31547508

Showing the first eight; more decompositions exist.
