Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147430718, here are decompositions:
- 29 + 2147430689 = 2147430718
- 89 + 2147430629 = 2147430718
- 101 + 2147430617 = 2147430718
- 131 + 2147430587 = 2147430718
- 281 + 2147430437 = 2147430718
- 347 + 2147430371 = 2147430718
- 401 + 2147430317 = 2147430718
- 479 + 2147430239 = 2147430718
Showing the first eight; more decompositions exist.
