Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294969990, here are decompositions:
- 11 + 4294969979 = 4294969990
- 41 + 4294969949 = 4294969990
- 83 + 4294969907 = 4294969990
- 89 + 4294969901 = 4294969990
- 251 + 4294969739 = 4294969990
- 257 + 4294969733 = 4294969990
- 263 + 4294969727 = 4294969990
- 347 + 4294969643 = 4294969990
Showing the first eight; more decompositions exist.
