Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560944, here are decompositions:

3 + 31560941 = 31560944
43 + 31560901 = 31560944
73 + 31560871 = 31560944
97 + 31560847 = 31560944
193 + 31560751 = 31560944
241 + 31560703 = 31560944
271 + 31560673 = 31560944
313 + 31560631 = 31560944

Showing the first eight; more decompositions exist.
