Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748432, here are decompositions:
- 13 + 8748419 = 8748432
- 19 + 8748413 = 8748432
- 29 + 8748403 = 8748432
- 71 + 8748361 = 8748432
- 73 + 8748359 = 8748432
- 101 + 8748331 = 8748432
- 103 + 8748329 = 8748432
- 109 + 8748323 = 8748432
Showing the first eight; more decompositions exist.
