Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43440, here are decompositions:

13 + 43427 = 43440
29 + 43411 = 43440
37 + 43403 = 43440
41 + 43399 = 43440
43 + 43397 = 43440
109 + 43331 = 43440
127 + 43313 = 43440
149 + 43291 = 43440

Showing the first eight; more decompositions exist.
