Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988646, here are decompositions:

3 + 988643 = 988646
67 + 988579 = 988646
97 + 988549 = 988646
157 + 988489 = 988646
163 + 988483 = 988646
193 + 988453 = 988646
229 + 988417 = 988646
349 + 988297 = 988646

Showing the first eight; more decompositions exist.
