Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154298, here are decompositions:

7 + 154291 = 154298
19 + 154279 = 154298
31 + 154267 = 154298
139 + 154159 = 154298
211 + 154087 = 154298
241 + 154057 = 154298
271 + 154027 = 154298
307 + 153991 = 154298

Showing the first eight; more decompositions exist.
