Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32440, here are decompositions:
- 11 + 32429 = 32440
- 17 + 32423 = 32440
- 29 + 32411 = 32440
- 59 + 32381 = 32440
- 71 + 32369 = 32440
- 113 + 32327 = 32440
- 131 + 32309 = 32440
- 137 + 32303 = 32440
Showing the first eight; more decompositions exist.
