Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84380, here are decompositions:

3 + 84377 = 84380
31 + 84349 = 84380
61 + 84319 = 84380
67 + 84313 = 84380
73 + 84307 = 84380
151 + 84229 = 84380
157 + 84223 = 84380
181 + 84199 = 84380

Showing the first eight; more decompositions exist.
