Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83642, here are decompositions:

3 + 83639 = 83642
79 + 83563 = 83642
193 + 83449 = 83642
199 + 83443 = 83642
211 + 83431 = 83642
241 + 83401 = 83642
331 + 83311 = 83642
373 + 83269 = 83642

Showing the first eight; more decompositions exist.
