Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561034, here are decompositions:

31 + 31561003 = 31561034
163 + 31560871 = 31561034
277 + 31560757 = 31561034
283 + 31560751 = 31561034
331 + 31560703 = 31561034
601 + 31560433 = 31561034
643 + 31560391 = 31561034
691 + 31560343 = 31561034

Showing the first eight; more decompositions exist.
