Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487774, here are decompositions:
- 17 + 2147487757 = 2147487774
- 23 + 2147487751 = 2147487774
- 71 + 2147487703 = 2147487774
- 73 + 2147487701 = 2147487774
- 83 + 2147487691 = 2147487774
- 137 + 2147487637 = 2147487774
- 151 + 2147487623 = 2147487774
- 163 + 2147487611 = 2147487774
Showing the first eight; more decompositions exist.
