Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547488, here are decompositions:

17 + 31547471 = 31547488
29 + 31547459 = 31547488
47 + 31547441 = 31547488
131 + 31547357 = 31547488
149 + 31547339 = 31547488
191 + 31547297 = 31547488
227 + 31547261 = 31547488
257 + 31547231 = 31547488

Showing the first eight; more decompositions exist.
