Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970978, here are decompositions:
- 139 + 4294970839 = 4294970978
- 229 + 4294970749 = 4294970978
- 409 + 4294970569 = 4294970978
- 457 + 4294970521 = 4294970978
- 601 + 4294970377 = 4294970978
- 631 + 4294970347 = 4294970978
- 829 + 4294970149 = 4294970978
- 919 + 4294970059 = 4294970978
Showing the first eight; more decompositions exist.
