Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560974, here are decompositions:

31 + 31560943 = 31560974
73 + 31560901 = 31560974
103 + 31560871 = 31560974
127 + 31560847 = 31560974
223 + 31560751 = 31560974
271 + 31560703 = 31560974
433 + 31560541 = 31560974
541 + 31560433 = 31560974

Showing the first eight; more decompositions exist.
