Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476298, here are decompositions:

47 + 31476251 = 31476298
59 + 31476239 = 31476298
149 + 31476149 = 31476298
179 + 31476119 = 31476298
239 + 31476059 = 31476298
281 + 31476017 = 31476298
389 + 31475909 = 31476298
449 + 31475849 = 31476298

Showing the first eight; more decompositions exist.
