Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577988, here are decompositions:

7 + 577981 = 577988
31 + 577957 = 577988
79 + 577909 = 577988
109 + 577879 = 577988
139 + 577849 = 577988
157 + 577831 = 577988
181 + 577807 = 577988
349 + 577639 = 577988

Showing the first eight; more decompositions exist.
