Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988782, here are decompositions:

19 + 988763 = 988782
23 + 988759 = 988782
71 + 988711 = 988782
89 + 988693 = 988782
101 + 988681 = 988782
131 + 988651 = 988782
139 + 988643 = 988782
191 + 988591 = 988782

Showing the first eight; more decompositions exist.
