Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83990, here are decompositions:

3 + 83987 = 83990
7 + 83983 = 83990
79 + 83911 = 83990
157 + 83833 = 83990
199 + 83791 = 83990
229 + 83761 = 83990
271 + 83719 = 83990
337 + 83653 = 83990

Showing the first eight; more decompositions exist.
