Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472298, here are decompositions:

5 + 31472293 = 31472298
7 + 31472291 = 31472298
37 + 31472261 = 31472298
59 + 31472239 = 31472298
89 + 31472209 = 31472298
97 + 31472201 = 31472298
107 + 31472191 = 31472298
131 + 31472167 = 31472298

Showing the first eight; more decompositions exist.
