Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747928, here are decompositions:
- 11 + 8747917 = 8747928
- 37 + 8747891 = 8747928
- 71 + 8747857 = 8747928
- 97 + 8747831 = 8747928
- 109 + 8747819 = 8747928
- 139 + 8747789 = 8747928
- 151 + 8747777 = 8747928
- 181 + 8747747 = 8747928
Showing the first eight; more decompositions exist.
