Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468298, here are decompositions:

67 + 31468231 = 31468298
97 + 31468201 = 31468298
139 + 31468159 = 31468298
151 + 31468147 = 31468298
271 + 31468027 = 31468298
331 + 31467967 = 31468298
349 + 31467949 = 31468298
487 + 31467811 = 31468298

Showing the first eight; more decompositions exist.
