Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185982, here are decompositions:

11 + 185971 = 185982
23 + 185959 = 185982
31 + 185951 = 185982
59 + 185923 = 185982
79 + 185903 = 185982
89 + 185893 = 185982
109 + 185873 = 185982
113 + 185869 = 185982

Showing the first eight; more decompositions exist.
