Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988458, here are decompositions:

5 + 988453 = 988458
19 + 988439 = 988458
41 + 988417 = 988458
101 + 988357 = 988458
137 + 988321 = 988458
139 + 988319 = 988458
179 + 988279 = 988458
227 + 988231 = 988458

Showing the first eight; more decompositions exist.
