Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957666, here are decompositions:
- 23 + 4294957643 = 4294957666
- 113 + 4294957553 = 4294957666
- 173 + 4294957493 = 4294957666
- 227 + 4294957439 = 4294957666
- 269 + 4294957397 = 4294957666
- 317 + 4294957349 = 4294957666
- 347 + 4294957319 = 4294957666
- 359 + 4294957307 = 4294957666
Showing the first eight; more decompositions exist.
