Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598200, here are decompositions:

59 + 31598141 = 31598200
167 + 31598033 = 31598200
173 + 31598027 = 31598200
191 + 31598009 = 31598200
239 + 31597961 = 31598200
461 + 31597739 = 31598200
479 + 31597721 = 31598200
503 + 31597697 = 31598200

Showing the first eight; more decompositions exist.
