Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978990, here are decompositions:
- 17 + 4294978973 = 4294978990
- 41 + 4294978949 = 4294978990
- 179 + 4294978811 = 4294978990
- 191 + 4294978799 = 4294978990
- 233 + 4294978757 = 4294978990
- 257 + 4294978733 = 4294978990
- 311 + 4294978679 = 4294978990
- 431 + 4294978559 = 4294978990
Showing the first eight; more decompositions exist.
