Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560196, here are decompositions:

23 + 31560173 = 31560196
89 + 31560107 = 31560196
137 + 31560059 = 31560196
149 + 31560047 = 31560196
167 + 31560029 = 31560196
347 + 31559849 = 31560196
383 + 31559813 = 31560196
419 + 31559777 = 31560196

Showing the first eight; more decompositions exist.
