Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560934, here are decompositions:

23 + 31560911 = 31560934
47 + 31560887 = 31560934
71 + 31560863 = 31560934
137 + 31560797 = 31560934
257 + 31560677 = 31560934
347 + 31560587 = 31560934
401 + 31560533 = 31560934
593 + 31560341 = 31560934

Showing the first eight; more decompositions exist.
