Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43402, here are decompositions:
- 3 + 43399 = 43402
- 5 + 43397 = 43402
- 11 + 43391 = 43402
- 71 + 43331 = 43402
- 83 + 43319 = 43402
- 89 + 43313 = 43402
- 131 + 43271 = 43402
- 179 + 43223 = 43402
Showing the first eight; more decompositions exist.
