Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988658, here are decompositions:

7 + 988651 = 988658
67 + 988591 = 988658
79 + 988579 = 988658
109 + 988549 = 988658
157 + 988501 = 988658
199 + 988459 = 988658
241 + 988417 = 988658
337 + 988321 = 988658

Showing the first eight; more decompositions exist.
