Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87394, here are decompositions:
- 11 + 87383 = 87394
- 71 + 87323 = 87394
- 101 + 87293 = 87394
- 113 + 87281 = 87394
- 137 + 87257 = 87394
- 173 + 87221 = 87394
- 311 + 87083 = 87394
- 353 + 87041 = 87394
Showing the first eight; more decompositions exist.
