Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425918, here are decompositions:
- 47 + 2147425871 = 2147425918
- 311 + 2147425607 = 2147425918
- 359 + 2147425559 = 2147425918
- 461 + 2147425457 = 2147425918
- 569 + 2147425349 = 2147425918
- 797 + 2147425121 = 2147425918
- 1019 + 2147424899 = 2147425918
- 1049 + 2147424869 = 2147425918
Showing the first eight; more decompositions exist.
