Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027888, here are decompositions:

5 + 1027883 = 1027888
47 + 1027841 = 1027888
89 + 1027799 = 1027888
101 + 1027787 = 1027888
131 + 1027757 = 1027888
137 + 1027751 = 1027888
149 + 1027739 = 1027888
401 + 1027487 = 1027888

Showing the first eight; more decompositions exist.
