Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998378, here are decompositions:

67 + 998311 = 998378
97 + 998281 = 998378
181 + 998197 = 998378
211 + 998167 = 998378
307 + 998071 = 998378
349 + 998029 = 998378
487 + 997891 = 998378
499 + 997879 = 998378

Showing the first eight; more decompositions exist.
