Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704680, here are decompositions:
- 29 + 8704651 = 8704680
- 59 + 8704621 = 8704680
- 67 + 8704613 = 8704680
- 71 + 8704609 = 8704680
- 73 + 8704607 = 8704680
- 79 + 8704601 = 8704680
- 113 + 8704567 = 8704680
- 157 + 8704523 = 8704680
Showing the first eight; more decompositions exist.
