Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598040, here are decompositions:

7 + 31598033 = 31598040
11 + 31598029 = 31598040
13 + 31598027 = 31598040
29 + 31598011 = 31598040
31 + 31598009 = 31598040
43 + 31597997 = 31598040
53 + 31597987 = 31598040
79 + 31597961 = 31598040

Showing the first eight; more decompositions exist.
