Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504298, here are decompositions:

79 + 31504219 = 31504298
97 + 31504201 = 31504298
109 + 31504189 = 31504298
211 + 31504087 = 31504298
337 + 31503961 = 31504298
367 + 31503931 = 31504298
457 + 31503841 = 31504298
487 + 31503811 = 31504298

Showing the first eight; more decompositions exist.
