Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186004, here are decompositions:

11 + 185993 = 186004
17 + 185987 = 186004
47 + 185957 = 186004
53 + 185951 = 186004
101 + 185903 = 186004
107 + 185897 = 186004
131 + 185873 = 186004
173 + 185831 = 186004

Showing the first eight; more decompositions exist.
