Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499298, here are decompositions:

7 + 31499291 = 31499298
31 + 31499267 = 31499298
59 + 31499239 = 31499298
67 + 31499231 = 31499298
71 + 31499227 = 31499298
109 + 31499189 = 31499298
137 + 31499161 = 31499298
139 + 31499159 = 31499298

Showing the first eight; more decompositions exist.
