Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547446, here are decompositions:

5 + 31547441 = 31547446
89 + 31547357 = 31547446
107 + 31547339 = 31547446
149 + 31547297 = 31547446
179 + 31547267 = 31547446
269 + 31547177 = 31547446
317 + 31547129 = 31547446
353 + 31547093 = 31547446

Showing the first eight; more decompositions exist.
