Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678670, here are decompositions:
- 31 + 8678639 = 8678670
- 67 + 8678603 = 8678670
- 71 + 8678599 = 8678670
- 83 + 8678587 = 8678670
- 89 + 8678581 = 8678670
- 113 + 8678557 = 8678670
- 151 + 8678519 = 8678670
- 163 + 8678507 = 8678670
Showing the first eight; more decompositions exist.
