Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998618, here are decompositions:

67 + 998551 = 998618
79 + 998539 = 998618
199 + 998419 = 998618
241 + 998377 = 998618
307 + 998311 = 998618
331 + 998287 = 998618
337 + 998281 = 998618
421 + 998197 = 998618

Showing the first eight; more decompositions exist.
