Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472798, here are decompositions:

211 + 31472587 = 31472798
349 + 31472449 = 31472798
439 + 31472359 = 31472798
607 + 31472191 = 31472798
619 + 31472179 = 31472798
631 + 31472167 = 31472798
691 + 31472107 = 31472798
757 + 31472041 = 31472798

Showing the first eight; more decompositions exist.
