Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598474, here are decompositions:

73 + 31598401 = 31598474
97 + 31598377 = 31598474
283 + 31598191 = 31598474
331 + 31598143 = 31598474
337 + 31598137 = 31598474
373 + 31598101 = 31598474
463 + 31598011 = 31598474
487 + 31597987 = 31598474

Showing the first eight; more decompositions exist.
