Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749340, here are decompositions:
- 3 + 8749337 = 8749340
- 31 + 8749309 = 8749340
- 97 + 8749243 = 8749340
- 199 + 8749141 = 8749340
- 349 + 8748991 = 8749340
- 367 + 8748973 = 8749340
- 463 + 8748877 = 8749340
- 487 + 8748853 = 8749340
Showing the first eight; more decompositions exist.
