Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186980, here are decompositions:

97 + 186883 = 186980
103 + 186877 = 186980
109 + 186871 = 186980
139 + 186841 = 186980
181 + 186799 = 186980
223 + 186757 = 186980
271 + 186709 = 186980
331 + 186649 = 186980

Showing the first eight; more decompositions exist.
