Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988622, here are decompositions:

31 + 988591 = 988622
43 + 988579 = 988622
73 + 988549 = 988622
139 + 988483 = 988622
163 + 988459 = 988622
379 + 988243 = 988622
409 + 988213 = 988622
571 + 988051 = 988622

Showing the first eight; more decompositions exist.
