Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971644, here are decompositions:
- 37 + 4294971607 = 4294971644
- 277 + 4294971367 = 4294971644
- 547 + 4294971097 = 4294971644
- 571 + 4294971073 = 4294971644
- 883 + 4294970761 = 4294971644
- 1123 + 4294970521 = 4294971644
- 1201 + 4294970443 = 4294971644
- 1297 + 4294970347 = 4294971644
Showing the first eight; more decompositions exist.
