Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988430, here are decompositions:

13 + 988417 = 988430
73 + 988357 = 988430
109 + 988321 = 988430
151 + 988279 = 988430
193 + 988237 = 988430
199 + 988231 = 988430
211 + 988219 = 988430
283 + 988147 = 988430

Showing the first eight; more decompositions exist.
