Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85990, here are decompositions:

59 + 85931 = 85990
101 + 85889 = 85990
137 + 85853 = 85990
173 + 85817 = 85990
197 + 85793 = 85990
239 + 85751 = 85990
257 + 85733 = 85990
347 + 85643 = 85990

Showing the first eight; more decompositions exist.
