Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600260, here are decompositions:

59 + 31600201 = 31600260
67 + 31600193 = 31600260
71 + 31600189 = 31600260
103 + 31600157 = 31600260
127 + 31600133 = 31600260
157 + 31600103 = 31600260
173 + 31600087 = 31600260
199 + 31600061 = 31600260

Showing the first eight; more decompositions exist.
