Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84180, here are decompositions:

17 + 84163 = 84180
37 + 84143 = 84180
43 + 84137 = 84180
53 + 84127 = 84180
59 + 84121 = 84180
113 + 84067 = 84180
127 + 84053 = 84180
163 + 84017 = 84180

Showing the first eight; more decompositions exist.
