Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547656, here are decompositions:

47 + 31547609 = 31547656
137 + 31547519 = 31547656
149 + 31547507 = 31547656
167 + 31547489 = 31547656
197 + 31547459 = 31547656
317 + 31547339 = 31547656
353 + 31547303 = 31547656
359 + 31547297 = 31547656

Showing the first eight; more decompositions exist.
