Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547498, here are decompositions:

19 + 31547479 = 31547498
181 + 31547317 = 31547498
211 + 31547287 = 31547498
337 + 31547161 = 31547498
397 + 31547101 = 31547498
421 + 31547077 = 31547498
607 + 31546891 = 31547498
691 + 31546807 = 31547498

Showing the first eight; more decompositions exist.
