Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978642, here are decompositions:
- 83 + 4294978559 = 4294978642
- 89 + 4294978553 = 4294978642
- 131 + 4294978511 = 4294978642
- 281 + 4294978361 = 4294978642
- 359 + 4294978283 = 4294978642
- 419 + 4294978223 = 4294978642
- 431 + 4294978211 = 4294978642
- 509 + 4294978133 = 4294978642
Showing the first eight; more decompositions exist.
