Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988838, here are decompositions:

79 + 988759 = 988838
127 + 988711 = 988838
157 + 988681 = 988838
337 + 988501 = 988838
349 + 988489 = 988838
379 + 988459 = 988838
421 + 988417 = 988838
541 + 988297 = 988838

Showing the first eight; more decompositions exist.
