Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598130, here are decompositions:

29 + 31598101 = 31598130
73 + 31598057 = 31598130
97 + 31598033 = 31598130
101 + 31598029 = 31598130
103 + 31598027 = 31598130
197 + 31597933 = 31598130
251 + 31597879 = 31598130
257 + 31597873 = 31598130

Showing the first eight; more decompositions exist.
