Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645364, here are decompositions:
- 5 + 8645359 = 8645364
- 11 + 8645353 = 8645364
- 23 + 8645341 = 8645364
- 37 + 8645327 = 8645364
- 71 + 8645293 = 8645364
- 83 + 8645281 = 8645364
- 97 + 8645267 = 8645364
- 103 + 8645261 = 8645364
Showing the first eight; more decompositions exist.
