Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474898, here are decompositions:

31 + 31474867 = 31474898
97 + 31474801 = 31474898
151 + 31474747 = 31474898
211 + 31474687 = 31474898
229 + 31474669 = 31474898
349 + 31474549 = 31474898
379 + 31474519 = 31474898
397 + 31474501 = 31474898

Showing the first eight; more decompositions exist.
