Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547506, here are decompositions:

17 + 31547489 = 31547506
47 + 31547459 = 31547506
149 + 31547357 = 31547506
167 + 31547339 = 31547506
239 + 31547267 = 31547506
359 + 31547147 = 31547506
443 + 31547063 = 31547506
467 + 31547039 = 31547506

Showing the first eight; more decompositions exist.
