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.
