Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988572, here are decompositions:

23 + 988549 = 988572
31 + 988541 = 988572
61 + 988511 = 988572
71 + 988501 = 988572
83 + 988489 = 988572
89 + 988483 = 988572
113 + 988459 = 988572
163 + 988409 = 988572

Showing the first eight; more decompositions exist.
