Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678824, here are decompositions:
- 3 + 8678821 = 8678824
- 41 + 8678783 = 8678824
- 47 + 8678777 = 8678824
- 71 + 8678753 = 8678824
- 83 + 8678741 = 8678824
- 131 + 8678693 = 8678824
- 317 + 8678507 = 8678824
- 431 + 8678393 = 8678824
Showing the first eight; more decompositions exist.
