Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943990, here are decompositions:

23 + 943967 = 943990
59 + 943931 = 943990
149 + 943841 = 943990
191 + 943799 = 943990
227 + 943763 = 943990
233 + 943757 = 943990
239 + 943751 = 943990
353 + 943637 = 943990

Showing the first eight; more decompositions exist.
