Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720436, here are decompositions:
- 5 + 8720431 = 8720436
- 7 + 8720429 = 8720436
- 19 + 8720417 = 8720436
- 29 + 8720407 = 8720436
- 47 + 8720389 = 8720436
- 89 + 8720347 = 8720436
- 97 + 8720339 = 8720436
- 317 + 8720119 = 8720436
Showing the first eight; more decompositions exist.
