Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988830, here are decompositions:

41 + 988789 = 988830
47 + 988783 = 988830
67 + 988763 = 988830
71 + 988759 = 988830
97 + 988733 = 988830
103 + 988727 = 988830
137 + 988693 = 988830
149 + 988681 = 988830

Showing the first eight; more decompositions exist.
