Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43454, here are decompositions:
- 3 + 43451 = 43454
- 13 + 43441 = 43454
- 43 + 43411 = 43454
- 163 + 43291 = 43454
- 193 + 43261 = 43454
- 277 + 43177 = 43454
- 337 + 43117 = 43454
- 487 + 42967 = 43454
Showing the first eight; more decompositions exist.
