Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723904, here are decompositions:
- 5 + 8723899 = 8723904
- 11 + 8723893 = 8723904
- 17 + 8723887 = 8723904
- 53 + 8723851 = 8723904
- 71 + 8723833 = 8723904
- 83 + 8723821 = 8723904
- 97 + 8723807 = 8723904
- 173 + 8723731 = 8723904
Showing the first eight; more decompositions exist.
