Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598444, here are decompositions:

43 + 31598401 = 31598444
67 + 31598377 = 31598444
307 + 31598137 = 31598444
433 + 31598011 = 31598444
457 + 31597987 = 31598444
571 + 31597873 = 31598444
601 + 31597843 = 31598444
643 + 31597801 = 31598444

Showing the first eight; more decompositions exist.
