Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84190, here are decompositions:

11 + 84179 = 84190
47 + 84143 = 84190
53 + 84137 = 84190
59 + 84131 = 84190
101 + 84089 = 84190
131 + 84059 = 84190
137 + 84053 = 84190
173 + 84017 = 84190

Showing the first eight; more decompositions exist.
