Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988560, here are decompositions:

11 + 988549 = 988560
19 + 988541 = 988560
59 + 988501 = 988560
71 + 988489 = 988560
101 + 988459 = 988560
107 + 988453 = 988560
151 + 988409 = 988560
193 + 988367 = 988560

Showing the first eight; more decompositions exist.
