Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704920, here are decompositions:
- 11 + 8704909 = 8704920
- 17 + 8704903 = 8704920
- 23 + 8704897 = 8704920
- 31 + 8704889 = 8704920
- 67 + 8704853 = 8704920
- 83 + 8704837 = 8704920
- 109 + 8704811 = 8704920
- 137 + 8704783 = 8704920
Showing the first eight; more decompositions exist.
