Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598738, here are decompositions:

37 + 31598701 = 31598738
337 + 31598401 = 31598738
439 + 31598299 = 31598738
499 + 31598239 = 31598738
547 + 31598191 = 31598738
601 + 31598137 = 31598738
709 + 31598029 = 31598738
727 + 31598011 = 31598738

Showing the first eight; more decompositions exist.
