Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678872, here are decompositions:
- 89 + 8678783 = 8678872
- 113 + 8678759 = 8678872
- 131 + 8678741 = 8678872
- 173 + 8678699 = 8678872
- 179 + 8678693 = 8678872
- 233 + 8678639 = 8678872
- 269 + 8678603 = 8678872
- 353 + 8678519 = 8678872
Showing the first eight; more decompositions exist.
