Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147424746, here are decompositions:
- 37 + 2147424709 = 2147424746
- 157 + 2147424589 = 2147424746
- 163 + 2147424583 = 2147424746
- 223 + 2147424523 = 2147424746
- 277 + 2147424469 = 2147424746
- 487 + 2147424259 = 2147424746
- 499 + 2147424247 = 2147424746
- 613 + 2147424133 = 2147424746
Showing the first eight; more decompositions exist.
