Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598088, here are decompositions:

31 + 31598057 = 31598088
59 + 31598029 = 31598088
61 + 31598027 = 31598088
79 + 31598009 = 31598088
101 + 31597987 = 31598088
127 + 31597961 = 31598088
211 + 31597877 = 31598088
311 + 31597777 = 31598088

Showing the first eight; more decompositions exist.
