Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998368, here are decompositions:

131 + 998237 = 998368
149 + 998219 = 998368
167 + 998201 = 998368
251 + 998117 = 998368
257 + 998111 = 998368
359 + 998009 = 998368
419 + 997949 = 998368
479 + 997889 = 998368

Showing the first eight; more decompositions exist.
