Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678400, here are decompositions:
- 7 + 8678393 = 8678400
- 37 + 8678363 = 8678400
- 41 + 8678359 = 8678400
- 47 + 8678353 = 8678400
- 61 + 8678339 = 8678400
- 67 + 8678333 = 8678400
- 89 + 8678311 = 8678400
- 163 + 8678237 = 8678400
Showing the first eight; more decompositions exist.
