Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45384, here are decompositions:
- 7 + 45377 = 45384
- 23 + 45361 = 45384
- 41 + 45343 = 45384
- 43 + 45341 = 45384
- 47 + 45337 = 45384
- 67 + 45317 = 45384
- 103 + 45281 = 45384
- 137 + 45247 = 45384
Showing the first eight; more decompositions exist.
