Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749936, here are decompositions:
- 89 + 8749847 = 8749936
- 149 + 8749787 = 8749936
- 347 + 8749589 = 8749936
- 467 + 8749469 = 8749936
- 479 + 8749457 = 8749936
- 593 + 8749343 = 8749936
- 599 + 8749337 = 8749936
- 773 + 8749163 = 8749936
Showing the first eight; more decompositions exist.
