Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988626, here are decompositions:

19 + 988607 = 988626
43 + 988583 = 988626
47 + 988579 = 988626
137 + 988489 = 988626
167 + 988459 = 988626
173 + 988453 = 988626
269 + 988357 = 988626
283 + 988343 = 988626

Showing the first eight; more decompositions exist.
