Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609958, here are decompositions:

97 + 31609861 = 31609958
109 + 31609849 = 31609958
139 + 31609819 = 31609958
181 + 31609777 = 31609958
199 + 31609759 = 31609958
349 + 31609609 = 31609958
397 + 31609561 = 31609958
409 + 31609549 = 31609958

Showing the first eight; more decompositions exist.
