Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598672, here are decompositions:

3 + 31598669 = 31598672
151 + 31598521 = 31598672
223 + 31598449 = 31598672
271 + 31598401 = 31598672
373 + 31598299 = 31598672
433 + 31598239 = 31598672
571 + 31598101 = 31598672
643 + 31598029 = 31598672

Showing the first eight; more decompositions exist.
