Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749392, here are decompositions:
- 61 + 8749331 = 8749392
- 83 + 8749309 = 8749392
- 149 + 8749243 = 8749392
- 163 + 8749229 = 8749392
- 173 + 8749219 = 8749392
- 193 + 8749199 = 8749392
- 229 + 8749163 = 8749392
- 241 + 8749151 = 8749392
Showing the first eight; more decompositions exist.
