Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560094, here are decompositions:

47 + 31560047 = 31560094
113 + 31559981 = 31560094
233 + 31559861 = 31560094
263 + 31559831 = 31560094
281 + 31559813 = 31560094
311 + 31559783 = 31560094
317 + 31559777 = 31560094
443 + 31559651 = 31560094

Showing the first eight; more decompositions exist.
