Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988778, here are decompositions:

19 + 988759 = 988778
67 + 988711 = 988778
97 + 988681 = 988778
127 + 988651 = 988778
199 + 988579 = 988778
229 + 988549 = 988778
277 + 988501 = 988778
421 + 988357 = 988778

Showing the first eight; more decompositions exist.
