Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147424670, here are decompositions:
- 29 + 2147424641 = 2147424670
- 107 + 2147424563 = 2147424670
- 113 + 2147424557 = 2147424670
- 137 + 2147424533 = 2147424670
- 239 + 2147424431 = 2147424670
- 311 + 2147424359 = 2147424670
- 317 + 2147424353 = 2147424670
- 359 + 2147424311 = 2147424670
Showing the first eight; more decompositions exist.
