Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669700, here are decompositions:
- 29 + 8669671 = 8669700
- 31 + 8669669 = 8669700
- 43 + 8669657 = 8669700
- 71 + 8669629 = 8669700
- 73 + 8669627 = 8669700
- 79 + 8669621 = 8669700
- 89 + 8669611 = 8669700
- 107 + 8669593 = 8669700
Showing the first eight; more decompositions exist.
