Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988590, here are decompositions:

7 + 988583 = 988590
11 + 988579 = 988590
13 + 988577 = 988590
19 + 988571 = 988590
41 + 988549 = 988590
79 + 988511 = 988590
89 + 988501 = 988590
101 + 988489 = 988590

Showing the first eight; more decompositions exist.
