Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598600, here are decompositions:

79 + 31598521 = 31598600
151 + 31598449 = 31598600
181 + 31598419 = 31598600
199 + 31598401 = 31598600
223 + 31598377 = 31598600
373 + 31598227 = 31598600
409 + 31598191 = 31598600
421 + 31598179 = 31598600

Showing the first eight; more decompositions exist.
