Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573298, here are decompositions:

19 + 31573279 = 31573298
37 + 31573261 = 31573298
109 + 31573189 = 31573298
241 + 31573057 = 31573298
271 + 31573027 = 31573298
277 + 31573021 = 31573298
349 + 31572949 = 31573298
397 + 31572901 = 31573298

Showing the first eight; more decompositions exist.
