Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988816, here are decompositions:

53 + 988763 = 988816
83 + 988733 = 988816
89 + 988727 = 988816
167 + 988649 = 988816
173 + 988643 = 988816
233 + 988583 = 988816
239 + 988577 = 988816
449 + 988367 = 988816

Showing the first eight; more decompositions exist.
