Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45378, here are decompositions:
- 17 + 45361 = 45378
- 37 + 45341 = 45378
- 41 + 45337 = 45378
- 59 + 45319 = 45378
- 61 + 45317 = 45378
- 71 + 45307 = 45378
- 89 + 45289 = 45378
- 97 + 45281 = 45378
Showing the first eight; more decompositions exist.
