Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147428670, here are decompositions:
- 109 + 2147428561 = 2147428670
- 151 + 2147428519 = 2147428670
- 181 + 2147428489 = 2147428670
- 307 + 2147428363 = 2147428670
- 337 + 2147428333 = 2147428670
- 523 + 2147428147 = 2147428670
- 571 + 2147428099 = 2147428670
- 577 + 2147428093 = 2147428670
Showing the first eight; more decompositions exist.
