Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576926, here are decompositions:

37 + 31576889 = 31576926
83 + 31576843 = 31576926
149 + 31576777 = 31576926
167 + 31576759 = 31576926
223 + 31576703 = 31576926
307 + 31576619 = 31576926
347 + 31576579 = 31576926
397 + 31576529 = 31576926

Showing the first eight; more decompositions exist.
