Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704878, here are decompositions:
- 41 + 8704837 = 8704878
- 67 + 8704811 = 8704878
- 101 + 8704777 = 8704878
- 157 + 8704721 = 8704878
- 167 + 8704711 = 8704878
- 179 + 8704699 = 8704878
- 191 + 8704687 = 8704878
- 227 + 8704651 = 8704878
Showing the first eight; more decompositions exist.
