Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43394, here are decompositions:
- 3 + 43391 = 43394
- 73 + 43321 = 43394
- 103 + 43291 = 43394
- 157 + 43237 = 43394
- 193 + 43201 = 43394
- 277 + 43117 = 43394
- 331 + 43063 = 43394
- 433 + 42961 = 43394
Showing the first eight; more decompositions exist.
