Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84072, here are decompositions:

5 + 84067 = 84072
11 + 84061 = 84072
13 + 84059 = 84072
19 + 84053 = 84072
61 + 84011 = 84072
89 + 83983 = 84072
103 + 83969 = 84072
139 + 83933 = 84072

Showing the first eight; more decompositions exist.
