Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598708, here are decompositions:

7 + 31598701 = 31598708
61 + 31598647 = 31598708
307 + 31598401 = 31598708
331 + 31598377 = 31598708
409 + 31598299 = 31598708
571 + 31598137 = 31598708
607 + 31598101 = 31598708
829 + 31597879 = 31598708

Showing the first eight; more decompositions exist.
