Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43390, here are decompositions:

59 + 43331 = 43390
71 + 43319 = 43390
107 + 43283 = 43390
167 + 43223 = 43390
239 + 43151 = 43390
257 + 43133 = 43390
353 + 43037 = 43390
401 + 42989 = 43390

Showing the first eight; more decompositions exist.
