Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597298, here are decompositions:

37 + 31597261 = 31597298
67 + 31597231 = 31597298
199 + 31597099 = 31597298
307 + 31596991 = 31597298
349 + 31596949 = 31597298
409 + 31596889 = 31597298
541 + 31596757 = 31597298
547 + 31596751 = 31597298

Showing the first eight; more decompositions exist.
