Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598908, here are decompositions:

41 + 31598867 = 31598908
137 + 31598771 = 31598908
191 + 31598717 = 31598908
239 + 31598669 = 31598908
317 + 31598591 = 31598908
389 + 31598519 = 31598908
449 + 31598459 = 31598908
491 + 31598417 = 31598908

Showing the first eight; more decompositions exist.
