Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422072, here are decompositions:
- 11 + 2147422061 = 2147422072
- 53 + 2147422019 = 2147422072
- 83 + 2147421989 = 2147422072
- 179 + 2147421893 = 2147422072
- 239 + 2147421833 = 2147422072
- 479 + 2147421593 = 2147422072
- 491 + 2147421581 = 2147422072
- 743 + 2147421329 = 2147422072
Showing the first eight; more decompositions exist.
