Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978868, here are decompositions:
- 139 + 4294978729 = 4294978868
- 241 + 4294978627 = 4294978868
- 277 + 4294978591 = 4294978868
- 379 + 4294978489 = 4294978868
- 487 + 4294978381 = 4294978868
- 541 + 4294978327 = 4294978868
- 619 + 4294978249 = 4294978868
- 787 + 4294978081 = 4294978868
Showing the first eight; more decompositions exist.
