Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600230, here are decompositions:

29 + 31600201 = 31600230
37 + 31600193 = 31600230
41 + 31600189 = 31600230
73 + 31600157 = 31600230
97 + 31600133 = 31600230
113 + 31600117 = 31600230
127 + 31600103 = 31600230
131 + 31600099 = 31600230

Showing the first eight; more decompositions exist.
